On another front, Fano resonance induced by strong plasmon–exciton coupling provides an efficient channel of coherent energy transfer from metallic plasmons to molecular excitons, and organic dye molecules have a much better injection efficiency in exciton-SSCs than “hot electrons”.

Plasmon-mediated energy transfer is highly desirable in photo-electronic nanodevices, but the direct injection efficiency of “hot electrons” in plasmonic photo-detectors and plasmon-sensitized solar cells (plasmon-SSCs) is poor. On another front, Fano resonance induced by strong plasmon…

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. This energy transfer from PNPs to semiconductors plays a decisive role in the overall photocatalytic performance. Plasmon resonance energy transfer (PRET) from a single metallic nanoparticle to the molecules adsorbed on its surface has attracted more and more attentions in recent years. Here, a molecular beacon (MB)‐regulated PRET coupling system composed of gold nanoparticles (GNPs) and chromophore molecules has been designed to study the influence of PRET effect on the scattering spectra of GNPs. This paper presents a new real-time electrodynamics approach for determining the rate of resonance energy transfer (RET) between two molecules in the presence of plasmonic or other nanostructures (inhomogeneous absorbing and dispersive media).

In this study, we overview resonance energy transfer between molecules in the presence of plasmonic structures and derive an explicit Forster type expression for the rate of plasmon-coupled resonance energy transfer (PC-RET). Surface plasmon energy can be transferred from Au nano-particles (AuNPs) as donors to dye molecules or semi-conductors as acceptors, through so-called plasmon-induced resonance energy transfer (PIRET) or plasmon resonance energy transfer (PRET).1−7 Compared with dye molecule donors in Förster resonance energy transfer (FRET), AuNP By tethering resonant biomolecules to Au nanoprobes, the binding events of Cytochrome c onto 50-nm Au nanoprobes yield characteristic spectral dips in scattering spectra of Au nanoprobes due to plasmon resonance energy transfer (PRET). Enhanced Förster resonance energy transfer was found for donor–acceptor pairs of cationic dyes in the presences of silver nanoparticles (NPs) in solution. This enhancement is attributed both to an increase in the fluorescence intensity of the dyes and the direct effect of local plasmon resonance of the NPs on the energy transfer rate constant.
