Förster resonance energy transfer, resonance energy transfer or electronic energy transfer is a mechanism describing energy transfer between two light-sensitive molecules. A donor chromophore, initially in its electronic excited state, may transfer energy to an acceptor chromophore through nonradiative dipole–dipole coupling. The efficiency of this energy transfer is inversely proportional to the sixth power of the distance between donor and acceptor, making FRET extremely Plasmon‐Enhanced Fluorescence Resonance Energy Transfer Huan Zong Computational Center for Property and Modification on Nanomaterials, College of Science, Liaoning Shihua University, Fushun, 113001 People's Republic of China We denote this process as plasmon-induced resonance energy transfer (PIRET) to distinguish the specific energy-transfer direction made possible by the plasmon from the more generalized FRET. In these composites, the plasmonic nanoparticles (PNPs) efficiently absorb solar light through localized surface plasmon resonance and convert it into energetic electrons and holes in the nearby semiconductor.
