Abstract
A new route to improve responsivity of reduced graphene oxide (rGO)-based near-infrared photodetectors is reported by coupling upconversion and gold plasmon. Near-infrared light is converted by upconversion nanoparticle into shorter wavelengths that can readily be absorbed by rGO. Further coupling of plasmonic layer increased upconversion emissions and rGO absorption, resulting in an overall enhancement of photo-responsivity by 10 times.Entities:
