The effect of reduced graphene oxide (rGO) on band edge UV emission of ZnO nanorods has been studied in the present work. For this purpose ZnO nanorods were grown by hydrothermal method on ITO substrate and a layer of rGO was spin coated over the as-grown nanorods. SEM and XRD measurements confirm the growth of vertically aligned ZnO nanorods over the substrate. Room temperature photoluminescence (RTPL) spectrum exhibit an enhanced UV emission of ZnO nanorods after incorporation of rGO. The improvement is ascribed to the surface plasmon resonance (SPR) effect at the ZnO/rGO interface. The plasmonic resonance leads to an enhanced absorption, which in turn results in the increased UV emission of the as grown nanorods.
