Abstract: 

In this investigation, CuInS2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. The CuCl, InCl3 along with (SC (NH2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (CH (CH2)17NH2) and oleic acid (CH (CH2)16COOH) as a coordination solvent and capping agent, respectively. The size, distribution and shape were optimized by controlling some parameters such as the ratio of solvent to capping agent, anion and cation solution temperature in the instant of injection. The crystal structure, morphology, and optical properties of synthesized nanoparticles were characterized using XRD, TEM, UV-VIS-NIR and PL. The results indicate that the temperature of the solution in the instant of injection has a significant effect on the tuning of the nanocrystals size as well as narrow size distribution.
