Graphene‐ZnS nanocomposites were prepared by hydrothermal method using functionalized graphene sheets (FGS) as matrix with Na 2 S and thioacetamide (TAA) as sulfide sources, respectively. The X‐ray diffraction (XRD) patterns reveal that face‐centered cubic ZnS was obtained. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results demonstrate different morphological characteristics of the two samples. The optical behaviors of both samples were examined by means of photoluminescence (PL) spectroscopy. The different effects of the two sulfide sources on the formation of the nanocomposites were also discussed to explain the reasons for the differences of morphological characteristics and optical behaviors between two samples.
