Abstract: The disclosed graphene quantum dot composite includes a dielectric matrix including a metal oxynitride, and a graphene quantum dot dispersed in the dielectric matrix. The graphene quantum dot composite can reduce the aggregation-caused photoluminescence quenching of graphene quantum dots, and can improve a photoluminescence quantum yields of a graphene quantum dot.
