Abstract
We report the distance-dependent energy transfer from an InGaN quantum well to graphene oxide (GO) by timeresolved photoluminescence (PL). A pronounced shortening of the PL decay time in the InGaN quantum well was observed when interacting with GO. The nature of the energy-transfer process has been analyzed, and we find the energy-transfer efficiency depends on the 1/d2 separation distance, which is dominated by the layer-to-layer dipole coupling.
