Two-dimensional (2D) composite nanostructures have received considerable attention for use in future ultrathin photodetectors. Hybrid 2D materials grown on graphene possess excellent dimensional-dependent properties, like low-cost fabrication and an environmentally friendly nature. Recently, semiconductor/graphene hybrid composite preparations are in development to enhance the light detection properties of graphene-related materials.[1] Cu2ZnSnS4 (CZTS) is a p-type material with a direct band gap energy of ~ 1–1.6 eV and high absorption coefficient (~104 cm−1). CZTS nanoparticles are potential materials for photodetecting applications.[2] In this article, we report the functionalization of a CZTS NP-decorated reduced graphene oxide (rGO) hybrid nanocomposite and their absorption properties were measured.
