▎ 摘  要

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 Zn(2+). 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. (C) 2011 Elsevier B.V. All rights reserved.
