▎ 摘  要

We demonstrate that longitudinal plasmons in doped monolayer graphene can mediate highly efficient long-range energy transfer between nearby fluorophores, e.g., semiconductor quantum dots. We derive a simple analytical expression for the energy transfer efficiency that incorporates all the essential processes involved. We perform numerical calculations of the transfer efficiency for a pair of PbSe quantum dots near graphene for interfluorophore distances of up to 1 mu m and find that the plasmon-assisted long-range energy transfer can be enhanced by up to a factor of similar to 10(4) relative to the Forster's transfer in vacuum.
