  4. Abstract:
  5. Chalcopyrite CuAlS2 nanoparticles were synthesized with polyol method. The solvothermal with autoclave nanoparticles synthesized are investigated. The amount and temperature of reducer, the solvent of salts could be important parameters that were studied. The nanoparticles were synthesized with CuCl, AlCl3 and thiourea (SC(NH2)2) as precursors, diethylene glycol ((CH2CH2 OH)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, scanning electron microscope (SEM) for morphology and by ultraviolet-visible (UV-VIS) spectrophotometer for analysis of light structure. The possible formation mechanism is also discussed
