Abstract

We report the temperature dependent photoluminescence (PL) properties of monolayer graphene–Au-nanoparticle–ZnO (GAZ) microwire hybrid structures. By comparing with the bare ZnO wire without coverage of graphene, a three times enhancement of PL was found in the GAZ hybrid structures. The enhancement is attributed to the coupling between the PL photons from ZnO and the graphene surface plasmons with ∼1–2 nm Au as a corrugated surface. Our results may be valuable for designing graphene–ZnO hybrid based optical and photoelectrical devices.
