Synthesis and Characterization of CuAlS2 Nanoparticles by Facile Heat Arrested Method

Abstract

CuAlS2 Chalcopyrite nanocrystalline are synthesized with facile method. The heat arrested solvothermal method for synthesize nanocrystalline were investigated. The time duration of synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters that we are studied. The nanoparticles were synthesized with CuCl, AlCl3 and thiourea (SC(NH2)2) as precursors, Diehylene glycol ((CH2CH2OH)2O) and Polyethylene glycol 600 (HO(C2H4O)nH) as solvent and capping agent respectively, and Ammonia (NH4OH) as reducing agent. The parameters of synthesis were studied by X-Ray diffraction (XRD) for analysis of structure and by ultraviolet–visible (UV-VIS) spectrophotometer for analysis of light structure. The possible formation mechanism metal complexes, sulfur ions and chalcopyrite compound are also discussed.
