CU2S nanostructures were prepared by thermolysis of the respective di-ethyldithiocarbamate single-source precursor solution in TOP on silicon substrates heated to 240-250 °C. As-obtained CU2S hexagonal nanoprisms were of ca. 150-250 nm size with band gap of ca. 1.1 eV. Smaller nanoprisms of ca. 50-100 nm diameter could be obtained by quenching the reaction with room temperature toluene. When the substrates were coated with a thin bismuth film, CU2S nanowires were obtained by the SLS growth mechanism.
