Solvothermal Synthesis of Phase-Pure CuInS2 Hierachical Nanostructure Using Single-Source Molecular Precursor

The synthesis of phase-pure CuInS2 microclusters comprising nanoflakes was achieved by solvothermal treatment of copper indium diethyldithiocarbamates (compositionally CuIn-(DDTC)5) in ethanol at 190 °C for 36 h. The obtained product was characterized by X-ray diffraction, Raman, energy dispersive X-ray spectroscopy and field emission scanning electron microscopy. Besides, contrast synthesis tests using multi-source precursors were also conducted.
