Abstract
This paper reports a hot colloidal synthesis method toward the synthesis of CuInS2/ZnS hybrid nanoparticles. First, CuInS2 quantum dots (QDs) were synthesized in the noncoordinating solvent octadecene using copper nitrate, indium acetate, myristic acid, oleylamine and dodecanethiol. CuInS2 QDs with diameter of 2~10 nm were obtained by tuning the reaction temperature and time. Secondly, CuInS2/ZnS core/shell QDs with different thickness of ZnS shell were synthesized by seed-mediated growth method, which can prevent the CuInS2 QDs oxidized and improve their photo luminance. Low-toxic cadmium-free CuInS2/ZnS QDs with high PL efficiency are expected to be used for bio-label.
