Abstract
Graphene–ZnS (G–ZnS) quantum dots nanocomposites were prepared by one pot solvothermal route. Graphite oxide (GO) was well dispersed in dimethyl sulfoxide (DMSO) solution of ions Zn2+, where DMSO acts as a sulphide source as well as reducing agent, resulting in the formation of graphene–ZnS quantum dot nanocomposites and simultaneous reduction of GO to graphene nanosheets. The size of the ZnS QDs in G–ZnS is around 10 nm, and the large 2D flexible atom-thin layer of graphene makes it easier to control the distribution of ZnS. The resulting G–ZnS QDs display a well-defined excitonic emission feature by luminescence analysis.
