Alloyed nanorods and hybrid nanostructures composed of CuInS2 and ZnS were synthesized by heating-up and hot-injection procedures. The synthesis starts with the formation of copper sulfide seeds, which are subsequently converted to copper sulfide – copper indium zinc sulfide hybrid nanostructures, by incorporation of indium and zinc ions. The fraction of ZnS within the alloyed material could be controlled by the amount of the Zn precursor in the reaction solution. In reactions with higher zinc precursor concentrations, at longer reaction times L-shaped hybrid nanostructures are formed of CuInS2-ZnS alloy and ZnS. An additional injection of the Zn-precursor into the reaction solution results in the formation of U-shaped hybrid nanostructures.
