This work presents a novel method to prepare graphene quantum dots (GQDs) directly from graphite.A composite film of GQDs and ZnO was first prepared using the composite target of graphite and ZnO via magnetron sputtering,followed with hydrochloric acid treatment and dialysis.Morphology and optical properties of the GQDs were investigated using atomic force microscope (AFM),transmission electron microscopy (TEM),UV-vis and fluorescence spectroscopy.
