Synergetically Enhanced Near-Infrared Photoresponse of Reduced Graphene Oxide by Upconversion and Gold Plasmon. Small, 10(18), 3637-3643. | Series/Report no.: | Small | 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 photoresponsivity by 10 times. | URI: | https://hdl.handle.net/10356/103478 http://hdl.handle.net/10220/24535 |
