Recently,it has been indicated that graphene nanosheet can emerge as an alternative,unique two-dimensional plasmonic material that displays a wide range of extraordinary properties.It is promising to fabricate graphene/QD nanocomposites by considering the excellent plasmonic properties of graphene and the photoelectronic properties of QDs.It has been indicated that the graphene can act as different roles in the photoluminescence of the hybrid nano structures.
