Co-precipitation route synthesized undoped ZnO and Sm-substituted ZnO nanomaterials are characterized using XRD, UV–Vis-NIR spectroscopy, Raman Spectroscopy, HRTEM and XAS techniques. Rietveld-refined XRD patterns and Raman spectra correspond to wurtzite structure similar to ZnO for all samples. For Sm-substituted ZnO samples, observed fluctuating lattice parameters suggest dopant-induced agitation in host lattice. Full incorporation of Sm cation can be seen by wurtzite ZnO nanolattice but for higher doping ,Sm cation is not fully incorporated and a new cubic phase of Sm2O3 is observed with our XRD and Raman analyses. From our TEM micrographs, particle sizes of undoped ZnO and Sm-substituted ZnO samples are found between 21 and 24 nm in spherical shape for undoped ZnO and nanorods for Sm-substituted ZnO samples. Absorption spectra analyses report a decrease in bandgap energy for Sm-substituted ZnO samples from 3.20 to 3.16 eV. X-ray absorption edges of Zn L2,3 edge, O K edge and Sm M4,5 edge measurements confirm the valence state of Sm cations is + 3 and the valence state of Zn ions is + 2 along with an increase in introduction of oxygen vacancies with Sm substitution in nanolattice. These nanoparticles can be suitable alternatives for various applications like oxygen transportation, UV blockers, photocatalyst and optoelectronics. [ABSTRACT FROM AUTHOR]

This paper reports the spectroscopic investigation of Ba3Zr2O7 phosphors. A series of Ba3Zr2O7: Eu3+ with the different molar concentrations (0–4 mol.%) of europium (Eu3+) ion is synthesized by the solution combustion method. The synthesized powders are characterized systematically using X-ray diffraction, X-ray photoelectron spectroscopy, photoluminescence spectroscopy, and ultraviolet–visible spectroscopy. X-ray diffraction results indicate that the synthesized powder has a tetragonal crystal structure. X-ray photoelectron spectroscopy is used to study the elemental composition of the synthesized phosphor. Field emission scanning electron microscopy result reveals that non-uniform morphology is formed. Photoluminescence spectroscopy result shows several emission peaks due to electronic transitions of Eu3+ ion, and the dominant peak is observed at 613 nm due to electric dipole transition 5D0 → 7F2. CIE coordinates of Eu3+-activated Ba3Zr2O7 phosphor is found to be (x = 0.64, y = 0.36) which gives bright red emission. The optical band gap of the phosphors is obtained from the diffuse reflectance spectrum and found in the range of 4.62–4.83 eV. [ABSTRACT FROM AUTHOR]

The synthesis and characterization of high mobility thin films of La-doped SrSnO 3 are reported. The mobility for the 7 % La-doped sample was found to be 228 cm 2 V - 1 s - 1 . The observed high mobility was associated with the reduced carrier effective mass and scattering centers of various scattering mechanisms. The enhancement in mobility and the increase in carrier concentration after doping reduced the resistivities of the thin films by five orders of magnitude. X-ray absorption spectroscopy and X-ray photoelectron spectroscopy revealed that La-dopant and oxygen vacancies donated the electrons in the films. Films were highly transparent (> 90 %) in the visible region. These materials have great potential to be used in optoelectronic and heterostructure devices [ABSTRACT FROM AUTHOR]

Anodized aluminum oxide (AAO) in amorphous form is shown to be a prospective phosphor for optically stimulated luminescence (OSL) by implanting 50 keV carbon ions at a fluence of 1 × 1016 ions/cm2 at room temperature. An almost 20-fold enhancement in continuous wave OSL (CW-OSL) sensitivity is obtained in carbon-doped AAO (C:AAO) by exposing to beta radiation, while an almost linear increase in CW-OSL intensity is recorded with increasing dose from 0.3 to 5 Gy. However, cathodoluminescence (CL) suggests an upsurge of oxygen vacancies, especially F+ and F22+ centers, at the cost of F center-related defects in C:AAO. Detailed X-ray photoelectron spectroscopy (XPS) analysis further reveals that the implanted carbon atoms can act as cationic impurities in AAO and stabilize the nearby F+ centers via substitution of Al3+ by C2+. The combined CL and XPS results are also shown to be capable of illustrating the CW-OSL response. This study would, therefore, be a benchmark for understanding the role of carbon in the substitutional sites of AAO for generating OSL active electron traps. [ABSTRACT FROM AUTHOR]

Two thin films of SrMnO3 (SMO) were grown on LAO (LaAlO3) (110) substrate by pulsed laser deposition (PLD) technique with different oxygen stoichiometry. From low-temperature magnetization measurements, it is observed that both films show a clear ferromagnetic kind of behavior. Electronic structure of both films has been investigated by using soft x-ray absorption spectroscopy (XAS) and photoemission spectroscopy (PES). It is revealed that the Mn-O hybridization is hugely modified due to oxygen stoichiometry, with its consequences on their magnetic properties. [ABSTRACT FROM AUTHOR]

Composites of Li1.3Al0.3Ti1.7(PO4)3 (LATP) with Li+ ion containing polymer polyethylene oxide (PEO), viz. 5LiCF3SO3-95[PEO1−xLATPx], are prepared in a wide composition range (0 ≤ x ≤ 0.7). A maximum conductivity of ~ 10−4 Ω−1 cm−1 at 45 °C has been achieved for a composition x = 0.7 (70 LATP). With increase in LATP content, Li+ ion transport number systematically increases, i.e., from ~ 0.12 for 0 LATP to 0.46 for 70 LATP. Ionic mobility also exhibits a gradual rise with LATP content and attains a value ~ 2 orders of magnitude higher for 70 LATP than 0 LATP. Further, the K-edge energy of ether oxygen, obtained from X-ray absorption near-edge structure spectra, does emphasize decoupling of Li+ ions from PEO matrix, particularly for large LATP content. Our investigations suggest that such hybrid films are competitive candidates for solid ionic devices. All-solid-state supercapacitors fabricated using these films demonstrate a capacity of ~ 2–4 F-g−1. [ABSTRACT FROM AUTHOR]

The polycrystalline ferroelectric compounds of general formula PbBaTiO with X = 0.00, 0.1, 0.2 and 0.5 were prepared by high temperature solid-state reaction technique using high purity oxides and carbonates. The compounds formation was confirmed by X-ray diffraction and all the X-ray peaks were indexed with tetragonal structure of space group P4 mm. Morphology and particle size of the compounds were obtained using scanning electron microscopy. Ferroelectric phase transition, enthalpy change, and specific heat of the compounds were obtained using modulated differential scanning calorimetry. It was observed that the phase transition temperature decreased linearly with the increase of substitution concentration. [ABSTRACT FROM AUTHOR]

Solid-state reaction synthesised K2Ti6O13 lead-free ceramic was characterized using XRD, SEM, and X-band EPR, at room temperature. EPR-spectra showed the presence of $$ \left( {{\text{Fe}}_{\text{Ti}}^{\prime } - V_{\text{O}}^{ \bullet \bullet } } \right) $$ defect associate dipoles, in orthorhombic phase, responsible for the broadening of the dielectric anomaly identified in the εr ( T) plots at T C ~ 300 °C. This anomaly resembled a ferroelectric–paraelectric type phase transition following Curie–Weiss type trend. Besides, dielectric loss mechanism jointly represented electrical conduction, dipole orientation, and space charge polarization. [ABSTRACT FROM AUTHOR]

Preparation of nanostructured tungsten oxide thin films using the reactive pulsed laser ablation technique is reported. The structural, morphological, optical and electrical properties of deposited films are systematically studied by changing the ambient oxygen pressure ( pO2). Structural dependence of tungsten oxide films on ambient oxygen pressure is discussed using grazing incidence X-ray diffraction (GIXRD) and micro-Raman spectra. The section analysis using atomic force microscopy exposed the smooth surface features of the deposited films. The blue shift in optical bandgap with an increase in ambient oxygen pressure is expounded in terms of electronic band structure of tungsten oxide. The influence of oxygen pressure on optical constants like extinction coefficient, band edge sharpness, refractive index and optical bandgap is also conveyed. The temperature variation of electrical resistance for films deposited at 0.12 mbar furnishes evidence for its semiconducting nature. [ABSTRACT FROM AUTHOR]

This work primarily is an investigation of the electronic structure properties of pure CeO2 and Ce 1 - x Gd x O 2 (x = 0.02, 0.04, 0.06, 0.08 and 0.10) Nanoparticles using the soft X-ray absorption spectroscopy were used to explore defects and vacancies. For this purpose, pure CeO2 and Ce 1 - x Gd x O 2 (x = 0.02, 0.04, 0.06, 0.08 and 0.10) nanomaterials were synthesized using the co-precipitation method. The XAS spectra at Ce M4,5, O K-edge and Gd M4,5 absorption edges clearly indicated a decrease in the valence state of Ce ions from Ce4+ to Ce3+ with the formation of oxygen vacancy defects upon incorporation of Gd3+ ions in CeO2 nanolattice. The results show meagre and sparse segregations of additive Gd+3 ions to form secondary phases in the samples. The deconvoluted Ce M4,5 peaks and O K-edge peaks clearly showed the existence of both oxidation states of Ce ions, Ce3+ and Ce4+,and also indicated the formation of oxygen vacancy defects in all the samples. The presence of Gd3+ oxidation state of Gd ions in Gd+3-doped CeO2 samples was investigated through Gd M4,5 edges. Furthermore, the origin of ferromagnetism in pure CeO2 and Gd3+-doped CeO2 samples is explained using F-centre exchange mechanism mediated by defects and oxygen vacancies. [ABSTRACT FROM AUTHOR]

We studied the structural and magnetic properties of in-situ grown iron mononitride (FeN) thin films. Initial stages of film growth were trapped utilizing synchrotron based soft x-ray absorption near edge spectroscopy (XANES) at the N K-edge and nuclear resonant scattering (NRS). Films were grown using dc-magnetron sputtering, separately at the experimental stations of SXAS beamline (BL01, Indus 2) and NRS beamline (P01, Petra III). It was found that the initial stages of film growth differs from the bulk of it. Ultrathin FeN films, exhibited larger energy separation between the t2g and eg features and an intense eg feature in the N K-edge pattern. This indicates that a structural transition is taking place from the rock-salt (RS)-type FeN to zinc-blende (ZB)-type FeN when the thickness of films increases beyond 5nm. The behavior of such N K-edge features correlates very well with the emergence of a magnetic component appearing in the NRS pattern at 100K in ultrathin FeN films. Combining the in-situ XANES and NRS measurements, it appears that initial FeN layers grow in a RS-type structure having a magnetic ground state. Subsequently, the structure changes to ZB-type which is known to be non-magnetic. Observed results help in resolving the long standing debate about the structure and the magnetic ground state of FeN.

Cyclic oxidation behavior of plasma-sprayed NiCrAlY, Ni-20Cr, Ni3Al, and Stellite-6 coatings was investigated in an aggressive environment of Na2SO4-60%V2O5 by thermogravimetric techniques for 50 cycles. These coatings were deposited on a Ni-base superalloy, namely Superni 600; 10Fe-15.5Cr-0.5Mn-0.2C-Bal Ni (wt.%). X-ray diffraction, scanning electron microscopy/energy dispersive x-ray (SEM/EDX), and electron probe microanalyzer (EPMA) techniques were used to analyze the oxidation products. The uncoated superalloy suffered accelerated oxidation in the form of intense spallation of its oxide scale. After deposition of the NiCrAlY coating, the superalloy showed a minimum mass gain, whereas after application of the Stellite-6 coating, a maximum mass gain was observed among the coatings studied. All of the coatings were found to be useful in reducing the spallation of the substrate superalloy. Moreover, the coatings were successful in maintaining continuous surface contact with the base superalloy during the cyclic oxidation. The phases revealed for the oxidized coatings were mainly the oxides of chromium and/or aluminum and the spinels containing nickel-chromium/cobalt-chromium/nickel-aluminum mixed oxides, which are reported to be protective against high-temperature oxidation/hot corrosion.

Fast recombination of photogenerated charge carriers is a major problem in the photoelectrochemical and photocatalytic processes. In this work, we report significantly improved PEC performance of a nanocomposite consists of In2S3 nanoparticles dispersed on g-C3N4 nanosheets synthesized by a simple and facile wet chemical route. The results of high-resolution TEM study show that the obtained In2S3 nanoparticles of size 10–20 nm exist in cubic phase and are uniformly dispersed on the surface of g-C3N4 nanosheets. The In2S3/g-C3N4 nanocomposite with 25 weight percentage of In2S3 exhibits 8.5 times higher photocurrent density than the single-phase g-C3N4 under visible light illumination.

The charge transfer mechanism in In2S3/g-C3N4 heterojunction was studied by a series of experiments, such as electrochemical impedance spectroscopy, photoelectrochemical measurement and photoluminescence emission spectroscopy.

The charge transfer mechanism in In2S3/g-C3N4 heterojunction was studied by a series of experiments, such as electrochemical impedance spectroscopy, photoelectrochemical measurement and photoluminescence emission spectroscopy. The intimate interface promotes the charge transfer and inhibits the recombination rate of photogenerated electron–hole pairs, which significantly improves the photoelectrochemical performance.

In this work, we report significantly improved PEC performance of a nanocomposite consists of In2S3 nanoparticles dispersed on g-C3N4 nanosheets synthesized by a simple and facile wet chemical route. The results of high-resolution TEM study show that the obtained In2S3 nanoparticles of size 10–20 nm exist in cubic phase and are uniformly dispersed on the surface of g-C3N4 nanosheets. The In2S3/g-C3N4 nanocomposite with 25 weight percentage of In2S3 exhibits 8.5 times higher photocurrent density than the single-phase g-C3N4 under visible light illumination. The enhanced photocurrent density exhibited by the In2S3/g-C3N4 nanocomposite is attributed to the efficient separation of photogenerated charge carriers. The charge transfer mechanism in In2S3/g-C3N4 heterojunction was studied by a series of experiments, such as electrochemical impedance spectroscopy, photoelectrochemical measurement and photoluminescence emission spectroscopy. The intimate interface promotes the charge transfer and inhibits the recombination rate of photogenerated electron–hole pairs, which significantly improves the photoelectrochemical performance. A detailed charge transfer mechanism is discussed based on the Mott–Schottky plot study. This heterojunction material is found to be an efficient photocatalyst for the degradation of both cationic rhodamine B dye and anionic methyl orange dye as the lifetime of photogenerated charge carriers is higher in the composite than in single-phase In2S3 and g-C3N4. A strong correlation between the photoelectrochemical and the photocatalytic performances is observed in this composite. [ABSTRACT FROM AUTHOR]
