【 摘 要 】

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