摘要：

Single crystalline CuInS2 particles with a chalcopyrite structure and a size of 7-10 nm were prepared by a convenient solvothermal reaction, and characterized by XRD, XPS, TEM (HR-TEM) and UV-vis absorption spectroscopy. The as-synthesized nanoparticles can be redispersed in organic solvents, which will facilitate the practical application of these nanoparticles under organic-solution conditions. The growth of the CuInS2 is regarded to involve the formation and decomposition of Cu2+-thiourea complexes, the reduction of Cu2+. and a slow supply of In3+ ions in the crystallization solution.
