We report a facile and efficient strategy for the preparation of graphene-Ag2Se nanocomposites. The reduction of graphene oxide (GO) to graphene was accompanied by the formation of Ag2Se particles on the surface of graphene nanosheets. The results of X-ray diffraction (XRD) and Fourier transform infrared (FTIR) confirmed the efficient reduction of GO. Transmission electron microscopy (TEM) images of the sample revealed the morphology of the architecture of graphene-Ag2Se hybrid. Photoluminescence (PL) measurement was further employed to study the optical properties of the nanocomposites. The results show that the graphene-Ag2Se nanocomposites can be prepared by a simple hydrothermal method, and Ag2Se particles are well distributed on the graphene nanosheets.
