摘　　要：A facile and efficient strategy was reported for the preparation of graphene nanosheets-Ag2S hybrid by a simple hydrothermal process. First, Ag2S particles deposited on the surface of graphene oxide（GO） sheet. GO was then reduced by hydrazine hydrate to graphene. The results of X-ray diffraction（XRD） and Fourier transform infrared（FTIR） demonstrated the efficient reduction of GO to graphene. Transmission electron microscopy（TEM） image of the sample reveals the morphology of the architecture of graphene-Ag2S hybrid. Ultraviolet-visible spectroscopy（UV-Vis） and photoluminescence（PL） measurement were further employed to study the optical properties of the obtained nanocomposite. This work can be extended to design other graphene-based hybrid nanomaterials, and the as-grown architectures may hold promise for many applications.A facile and efficient strategy was reported for the preparation of graphene nanosheets-Ag2S hybrid by a simple hydrothermal process.
