Abstract
Shape-controlled ZnS–graphene oxide (GO) nanocomposites were successfully synthesized via an easy one-step hydrothermal method by changing the solvents. The sample prepared in ethytleneglycol and water (1:1 in volume ratio) yielded ZnS nanoparticles (NPs)–GO nanocomposites. The sample prepared in ethylenediamine and water (1:1 in volume ratio) yielded ZnS nanowires (NWs)–GO nanocomposites. The sample prepared in ethytleneglycol, ethylenediamine and water (1:1:2 in volume ratio) yielded ZnS nanorods (NRs)–GO nanocomposites. The results showed that the GO in the composite were exfoliated and decorated with ZnS NPs, NWs and NRs. The photoluminescence intensity of the ZnS–GO nanocomposites exhibited a clearly quenching in comparison with that of ZnS.
