In this investigation, (1,8-diamino-3,6-dioxaoctan)copper(II)sulfate, ([Cu(DADO)]SO), bis(propylenediamine)copper(II)sulfate, and ([Cu(pn)]SO) were applied as copper precursors to fabricate CuInS (CIS) nanostructures in presence of microwave irradiation. Besides the effect of copper precursor, the effect of microwave power and time of irradiation on morphology of CuInS nanostructures were investigated. The as-prepared products were analyzed by XRD, PL, FT-IR, EDS, and SEM. The results of XRD patterns were indicated that pure CuInS with tetragonal phase could be only obtained after annealing at 400 °C for 2 h in a mixture of 85 % Ar and 15 % H gases. SEM images were shown that regular hierarchical nanostructures of CuInS were obtained with the aid of [Cu(pn)]SO as copper precursor under 900 W irradiation power for 12 min. The photovoltaic behaviors of as-synthesized CuInS nanostructures were studied after deposition of CdS film on chemical bath. CuInS film was directly deposited on the surface of the CdS film through doctor blade method. The as-deposited CdS/CuInS films were applied in photovoltaic measurements. [ABSTRACT FROM AUTHOR]

For the first time, a Schiff base compound derived from 1,8-diamino-3,6-dioxaoctane and 2-hydroxybenzophenone marked as (2-HBP)-(DaDo) was synthesized, characterized and then used as capping agent for the preparation of PbTe micro/nanostructures. Besides the as-synthesized Schiff base compound, Pb(NO) and Te powders were applied as lead and telluride precursors. In addition, effect of preparation parameters like reaction time and temperature in hydrothermal synthesis on the morphology of the final products was tested. The products were analysed with the aid of SEM, XRD, FT-IR and EDS. Based on the obtained results, it was found that pure cubic phased PbTe has been obtained by this method. According to SEM images, it was found that uniform PbTe micro/nanocubes have been obtained at 180 °C for 12 h. On the other hand, by increasing the reaction temperature from 3 to 24 h, the production of cubic-like shapes increased. [ABSTRACT FROM AUTHOR]

Abstract: In this work, pomegranate juice was used not only as reductant, but also as capping agent for self-assembly of trigonal nanostructures to form flower-like CuI microstructures. Pomegranate juice was applied as reductant because of the presence of anthocyanin molecules in its ingredients. Besides pomegranate juice, Cu(NO3)2.3H2O and LiI were used as copper and iodide sources for the preparation of CuI nanostructures via a simple precipitation method at ambient conditions. By using different amounts of pomegranate juice, various morphologies of CuI have been obtained. It was found that uniform flower-like CuI microstructures composed of trigonal nanostructures have been successfully produced using 8mL of pomegranate juice. [Copyright &y& Elsevier]

Abstract: In this work, nanostructured PbSe materials have been prepared via a solvothermal method at 180°C with the aid of new lead precursors like Schiff-base compounds; Pb(salpn) and Pb(salophen). Besides lead complexes as lead precursor, SeCl4, and N2H4·H2O as starting materials and propylene glycol as solvent were applied. On the other hand, the effect of preparation factors such as type of reducing and capping agent on the morphology of PbSe nanostructures was investigated. The as-prepared PbSe nanostructures were characterized by XRD, SEM, TEM, EDS, and FT-IR. The SEM micrographs of the products indicated that PbSe nanostructures with lower particle size were obtained after solvothermal treatment for 3h at 180°C in the presence of hydrazine hydrate as reducing agent. The as-obtained results indicated that pure and homogeneous PbSe nanostructures have been form by using Pb(salpn) as precursor. [Copyright &y& Elsevier]
