Synthesis, characterization and optical properties of graphene sheets-ZnO multipod nanocomposites

► GSs and GSs-ZnO multipod nanocomposite have been synthesized. ► Solvothermal and hydrothermal methods have been employed for above synthesis. ► The PL emission peak was quenched completely for GSs-ZnO multipod anocomposite. ► It would be intriguing to explore the origin of this fluorescence quenching property.
