Near-infrared (NIR) mechanoluminescence (ML) materials have been of great interest within biological tissues due to their biocompatibility and suitability for biostress imaging. However, the reported NIR MLs have predominantly been featured with narrowband ML emissions, which may limit their further applications. In this work, a novel broadband NIR ML material of Lu 3 Ga 4.88 O 12 :0.12Cr3+ (FWHM > 120 nm) is reported. By substituting Al3+ for Ga3+, the local crystal field strength and the defect concentration are reasonably regulated, which further improves the NIR ML (650–1000 nm) intensity of Cr3+ ion by 475 %. In addition, by compounding polydimethylsiloxane with this phosphor, the obtained Cr3+ NIR ML film can penetrate 10 mm pork tissues quite well, indicating potential applications for stress distribution optical imaging within living organisms. Expectingly, broadband NIR ML from Cr3+ ions can be obtained by further solid-solution multiple lattice sites substitution, which may provide a new approach to improve the performance of NIR ML materials towards expanded biological applications. [Display omitted] • Broadband near-infrared mechanoluminescence is obtained by utilizing the d-d transition of Cr3+ ion. • Improved mechanoluminescence intensity by substituting Al3+ for Ga3+. • Dependence between mechanoluminescence and defect concentration was confirmed. • Potential application in biostress imaging has been demonstrated.

A large-sized zero-valent iron plate (LSZVIP) with excellent reaction efficiency and cycle performance for heavy-metal ion removal from wastewater is desirable. However, it has yet to be achieved due to its relatively low specific surface area and non-crystal oxide shells produced during treatment, preventing its core electrons from transporting to the shell surface for heavy-metal ion reduction. Therefore, we proposed a novel mechanism to address the challenges in this paper by earthing the iron plate and stirring the treated solution to trigger an insulator-to-metal transition in the non-crystal oxides shell, thereby removing the barrier to electron transport in the oxide shells. Furthermore, earthing of the iron plate allows electrons from the earth to participate in hexavalent chromium (Cr(VI)) reduction, thereby eliminating the production of oxide shells during the reduction. With the stirring and earthing strategy, an acceptable Cr(VI)-reduction performance is obtained over the decimeter-sized zero-valent iron plate (DSZVIP). The residence time of earthing DSZVIP in the 1st cycle is 25 min and 80 min in the 10th cycle by stirring at 350 rotations per minutes (rpm) to achieve 100% Cr(VI)-reduction. This study provides a novel and applicable method for treating heavy-metal wastewater on a large scale. • Utilizing a decimeter-sized zero-valent iron plate (DSZVIP) to reduce Cr(VI) and obtain an satisfactory Cr(VI)-reduction performance for application, including high reduction efficiency and good cycle performance, through two strategies: stirring Cr(VI) solution and earthing the DSZVIP. • Drive an insulator-to-metal transition in the non-crystal iron oxide shell of DSZVIP for the reduction of heavy metal ions by stirring. • Earthing the DSZVIP for improving the Cr(VI)-reduction cycle performance since stirring could trigger an insulator-metal transition in non-crystal oxides shell, thus removing the obstacle of electrons-transportation in oxides shell. Earthing of iron plate introduce electrons from the earth to participate Cr(VI) reduction of and therefore eliminates the production of oxide shell during Cr(VI) reduction. [ABSTRACT FROM AUTHOR]

Abstract: The surface treatment effects of sapphire substrate on the quality of epitaxial ZnO thin films grown by metal-organic chemical vapor deposition (MOCVD) were studied. The sapphire substrates have been investigated by means of atomic force microscopy (AFM) and X-ray diffraction rocking curves (XRCs). The results show that sapphire substrate surfaces have the best-quality by CMP with subsequent chemical etching. The surface treatment effects of sapphire substrate on the ZnO thin films were examined by X-ray diffraction (XRD), atomic force microscopy (AFM) and photoluminescence (PL) measurements. Results show that the intensity of (002) diffraction peak of ZnO thin films on sapphire substrates treated by CMP with subsequent chemical etching is strongest. FWHM of (002) diffraction peak is narrowest and the intensity of UV peak of PL spectrum is strongest, indicating surface treatment on sapphire substrate preparation may improve ZnO thin films crystal quality and photoluminescent property.

Abstract: ZnO films were grown on (0001) LiNbO3 substrates by metal organic chemical vapor deposition (MOCVD). Annealing of ZnO films was performed in air for 1h at 800°C. The effects of annealing on the structural and optical properties of ZnO thin films on LiNbO3 substrates were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM) and photoluminescence (PL) measurements. XRD patterns and AFM showed that the as-grown and the annealed ZnO films grown on LiNbO3 substrates had c-axis preferential orientation, the crystallinity of the ZnO films grown on LiNbO3 substrates was improved, and the grain size increased by annealing. The PL spectra showed that the intensity of the UV near-band-edge peak was increased after annealing, while the intensity of visible peak (deep-level emission) decreased. [Copyright &y& Elsevier]

Abstract: ZnO thin films were grown on (0001) LiNbO3 substrates by the MOCVD technique. The substrate temperatures during growth were changed from 400 to 600°C. The X-ray diffraction (XRD) pattern of the ZnO film showed a strong [002] reflection peak, and the peak intensity was dependent on substrate temperature. The ZnO columnar grains were highly oriented along the (002) direction when the film processing temperature was 600°C. The optical transmission and PL results also indicated that highest crystalline quality of the ZnO films could be obtained at elevated temperatures. [Copyright &y& Elsevier]

Abstract: Ce-coped Lu2SiO5 powders were prepared by the solid-state reaction method. The effects of flux and atmosphere on the powders structure and properties were investigated by X-ray diffraction (XRD) and spectral measurement. The XRD results show that the samples calcined at 1300°C without using flux were mainly Lu2O3, SiO2 and a small amount of Lu2SiO5, while the samples with Li2SO4 flux are mainly Lu2SiO5. Furthermore, atmosphere is little effective on powder structure. Absorption band of Lu2SiO5 powders shows five peaks at 215nm, 241nm, 275nm, 318nm and 382nm, the absorption intensity of samples prepared in air is higher than that of samples prepared in reduced atmosphere. Broad emission band and stronger emission intensities have been found in Lu2SiO5 powders prepared in reduced atmosphere. The excitation spectra of Lu2SiO5 powders prepared in reduced atmosphere are composed of four bands at 240nm, 271nm, 302nm and 360.6nm. It can be concluded that flux and atmosphere during preparation is favorable for LSO powders emission and is an effective method to decrease calcining temperature. [Copyright &y& Elsevier]

Emission spectra of GSO:Ce films were measured, results exhibit the characteristic blue emission peak at 427nm. [Copyright &y& Elsevier]

Zn 2 SnO 4 (ZTO)/ZIF-8 nanocomposite photocatalysts were prepared by solution method and hydrothermal method. The structures and properties of ZTO/ZIF-8 nanocomposites were studied. Results indicate that ZTO is adsorbed on the surface of ZIF-8 after recombination. The addition of ZIF-8 can inhibit the recombination of photoelectron-hole pairs, which significantly improve the photocatalytic activity of ZTO. After the addition of ZIF-8, the adsorption performance of the composite is slightly improved, which is attributed to the high specific surface area of ZIF-8. In the removal efficiency of 20 mg/L MB dye solution, the photocatalytic activity of ZTO/0.4 wt%ZIF-8 nanocomposite is 75% after 120 min. In addition, the structural stability and cyclic properties of ZTO/ZIF-8 are investigated, and the degradation efficiency is still 71% after four cycles. [ABSTRACT FROM AUTHOR]

Abstract: Lattice-matched (Δa/a=1.8–3.4%) (001) LiGaO2 substrates have been employed for the first time to grow ZnO thin films by pulsed-laser deposition at 350–650°C with oxygen partial pressure of 20Pa. XRD shows that a highly c-axis-oriented ZnO film can be deposited on (001) LiGaO2 substrate at 500°C. AFM images reveal the surfaces of as-deposited ZnO films are smooth and root-mean-square values are 6.662, 5.765 and 6.834nm at 350, 500 and 650°C, respectively. PL spectra indicate only near-band-edge UV emission appears in the curve of ZnO film deposited at 500°C. The deep-level emission of ZnO film deposited at 650°C probably results from Li diffusion into the film. All the results illustrate substrate temperature plays a pretty important role in obtaining ZnO film with a high quality on LiGaO2 substrate by pulsed-laser deposition. [Copyright &y& Elsevier]

Te4+-doped CaYAlO 4 samples had a tetragonal crystal structure and emit deep-red light at 715 nm excited by 325 nm, which was ascribed to Te4+ luminescence center. The luminescent intensity of CaYAlO 4 : Te4+ samples increased with the sintering temperature increasing, reaching a maximum at 1500 °C, then began to drop. The optimal Te4+ doping concentration was 2 mol%. Lifetime of CaYAlO 4 : 2%Te4+ phosphors was 1.54 ms.

The PL intensity is 14 times stronger with the incorporation of 80 mol.% Y, and the 5D 4 →7F 5 emission lifetime of Tb3+ is prolonged from 0.357 to 3.035 ms at room temperature. A unique magnetoluminescence emerges upon the incorporation of Y, showing an interesting emission decrease to 55% as the Y content reaches 80 mol.%. Remarkably, this magnetoluminesence can occur at room temperature without an intense magnetic field.

In particular, the magnetoluminescence provides a simple, noncontact and nondestructive route for probing magnetic fields. [ABSTRACT FROM AUTHOR]

Sm3+ and Sm3+/Eu3+ doped Li 6 Gd(BO 3) 3 (LGBO) powders were prepared by solid-state reaction. The microstructure, luminescent characteristics, energy transfer and fluorescence lifetimes were studied. Gd3+ can absorb energy and transfer it to Sm3+ under 278 nm excitation, which increases the luminescent intensity of Sm3+ at 567, 611 and 649 nm. Under 405 nm excitation, the 4G 5/2 -6H 5/2 transition belonging to Sm3+ and the 5D 0 -7F 2 transition belonging to Eu3+ appear in the emission spectra of Sm3+/Eu3+ co-doped LGBO phosphors, glowing yellow-orange and red light, respectively. The mechanism behind the energy transfer was analyzed, and the energy transfer efficiency was calculated to be 31.2% when the Sm3+ concentration reached 4mol%. The LGBO:Sm3+/Eu3+ phosphors have prospective applications in solid-state lighting, display devices, bio-imaging, etc. • The obtained Li 6 Gd(BO 3) 3 :Sm3+/Eu3+ phosphor has excellent luminescent properties. • Sm3+ acts as a sensitizer which extends the excitation range of Eu3+ in the near-uv and enhances Eu3+ emission. • The Li 6 Gd(BO 3) 3 :Sm3+/Eu3+ phosphor can emits a stronger orange-red light due to the energy transfer of Sm3+ to Eu3+. • The energy transfer efficiency from Sm3+ to Eu3+ can reach 31.2%.

A one-step microwave irradiation method was used to deposit carbon and nitrogen co-doped TiO 2 ((C, N)-TiO 2 ) on commercial brick ((C, N)-TiO 2 /brick). The as-prepared samples were characterized by X-ray diffraction, ultraviolet–visible (UV–vis) diffuse reflectance spectroscopy, photoluminescence spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy (SEM). A selective technique was also used to investigate the concentration of hydroxyl radicals during UV–vis irradiation of the Methyl Orange solution with the as-prepared samples. The C and N dopants enhanced visible light absorption and provided a longer lifetime for the photo-generated electron–hole pairs. The SEM images showed that the as-prepared sample is porous. The dark adsorption and photodegradation test for (C, N)-TiO 2 /brick showed good photodegradation and good recyclability. The best photodegradation rate was 94% after 2 hr. The maximum degradation rate was maintained even after the 6th cycle. The good photocatalytic properties are attributed to the enhanced visible light absorption, enhanced pollutant adsorption arising from the porous structure of the (C, N)-TiO 2 thin film, and longer lifetime of the photo-generated electron–hole pairs. (C, N)-TiO 2 /brick should have potential commercial applications in photodegradation processes because of its low cost, good photodegradation, and excellent recyclability. [ABSTRACT FROM AUTHOR]

In this study, SnS 2 /S-doped g-C 3 N 4 (Sg-C 3 N 4) composite with SnS 2 and Sg-C 3 N 4 in the weight ratio of 9:1 was prepared by a hydrothermal method. For comparison, composites of SnS 2 /Sg-C 3 N 4 with weight ratios of 9:0.05 and 9:1.5, pure SnS 2 , Sg-C 3 N 4 , and g-C 3 N 4 were also prepared using the same processing parameters. Microstructural characterization showed that nano-sized SnS 2 particles were deposited on Sg-C 3 N 4 to form a Z-scheme photocatalyst. The chemical valence of the doped S in Sg-C 3 N 4 was +6, allowing the surface of Sg-C 3 N 4 in the composite to be considerably uneven for the deposition of SnS 2. The uneven surface of Sg-C 3 N 4 resulted in a rough surface of the SnS 2 /Sg-C 3 N 4 composite, which significantly enhanced the specific surface area and light absorption over a wide wavelength range of 200–1000 nm. The carrier transfer capability and lifetime of g-C 3 N 4 were improved after S doping. The lifetime and transfer ability of the photoproduced carriers in the composite were improved by the Z-scheme heterojunction. Consequently, the rate constant of the composite is thrice that of pure SnS 2 and 57 times that of Sg-C 3 N 4. This work demonstrates a novel route to enhance light absorption over a wide wavelength range: depositing a semiconductor on a base semiconductor with an uneven surface charge distribution can produce a composite with a rough surface, i.e., a large specific surface area. • SnS 2 /S-doped g-C 3 N 4 (Sg-C 3 N 4) composite was prepared for the first time. • The chemical valence of doped S in Sg-C 3 N 4 was 6+, allowing the surface of Sg-C 3 N 4 in the composite to be considerably uneven for the deposition of SnS 2. • The rate constant of the composite is thrice that of pure SnS 2 and 57 times that of Sg-C 3 N 4. • A novel route to enhance light absorption over a wide wavelength range: depositing a semiconductor on a base semiconductor with an uneven surface charge distribution can produce a composite with a rough surface, i.e., a large specific surface area.

A novel, magnetic, p – n heterojunction-structured La 0.7 Sr 0.3 MnO 3 /g-C 3 N 4 (LS/CN) photocatalyst was designed by hybridizing p -type La 0.7 Sr 0.3 MnO 3 with n -type g-C 3 N 4. Several characterizations showed that the as-preparedLS/CN-0.5 nanoparticles possessed a saturation magnetization of 27.3 emu/g, coercivity of 60.3 Oe, specific surface area of 25.68 m2/g, and average particle size of 23 nm. The photocatalytic investigation determined a degradation efficiency of 95.0% for a 100-mL tetracycline solution with an initial concentration of 50 mg/L within 210 min over 0.05 g of the LS/CN-0.5. Experiments showed that LS/CN-0.5 exhibited good reusability, where a degradation efficiency of 88.6% was obtained after six cycles.

• A novel α-SnWO 4 /UiO-66(NH 2)/g-C 3 N 4 ternary photocatalyst was prepared by solvothermal method. • The α-SW 75 /UNCN exhibits the superior photocatalytic performance for Ibuprofen degradation and H 2 evolution. • The •O 2 - and •OH are confirmed as the main reactive species. • The possible mechanism of photocatalytic was explored. [Display omitted] In this work, we successfully prepared regular hexagonal prism porous structure g-C 3 N 4 (CN), and designed α-SnWO 4 and UiO-66(NH 2) on porous CN for constructing novel ternary α-SnWO 4 /UiO-66(NH 2)/g-C 3 N 4 (α-SW/UNCN) hybrid photocatalyst by solvothermal approach. The α-SW 75 /UNCN composite showed better photocatalytic performance, and the removal rate of Ibuprofen (IPF) reached 95.5% within 2 h and the H 2 evolution efficiency reached 2105 μmol g−1 h−1 under simulated sunlight, which were 2.5 times and 21 times higher than those of α-SW (42.5% and 105 μmol g−1 h−1). The TOC removal efficiency of IPF can reach to 29%, showing higher mineralization ability compared with α-SW. In addition, the trapping experiment and ESR experiment proved that •O 2 - and •OH radicals played most important part in the photodegradation of IPF pollutants. The improved photocatalytic performance of α-SW/UNCN was owing to the construction of n-p-n type double Z-scheme heterojunction which enhanced carries separation.
