Preparation of Ag2S-Graphene nanocomposite from a single source precursor and its surface-enhanced Raman scattering and photoluminescent activity

► Ag2S nanoparticles are deposited on graphene sheets via a single source precursor. ► Graphene oxide is reduced to graphene in the hydrothermal reaction process. ► Ag2S-Graphene system displays surface-enhanced Raman scattering activity and relatively better fluorescence property.
