Plasmon effects on linear spectra related to heterogeneous electron transfer

Abstract

By considering the effect of molecular vibrational states, a system of dye semi-conductor coupled with metal nano-particle linear absorption spectra and its electron transfer dynamics are studied in dipole-dipole approximation. As the results of the coupling of metal nano-particle, a wider absorption spectrum and the enhancement of electron transfer have been achieved. Effects of nano-metal surface plasmons on the ultrafast heterogeneous electron transfer are discussed in detail.
