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...
