Abstract

CuInS ₂ nanoparticles were synthesized by thermal decomposition of a mixture of [Cu(SON(CN ⁱPr ₂) ₂) ₂] and [In(SON(CN ⁱPr ₂) ₂) ₃] in oleylamine and/or dodecanethiol. X-ray diffraction showed that chalcopyrite (tetragonal) CuInS ₂, wurtzitic (hexagonal) CuInS ₂, or chalcopyrite with minor amount of wurtzitic phases could be obtained by varying the reaction conditions. Changing the reaction conditions could also control the morphology of the CuInS ₂ nanoparticles (spherical, hexagonal, trigonal or conical). Luminescent CuInS ₂ nanoparticles were obtained only in the absence of oleylamine. Wurtzite-chalcopyrite polytypism was observed in one of the samples by high-resolution transmission electron microscopy.
