The Enhancement of Molecular Fluorescence and Photochemistry by Small Metal Particles.
Abstract
We examine a quantum mechanical model for the enhancement of fluorescence yield and photochemical rates by the presence of small particle capable to sustain electromagnetic resonances. The sphere lowers the absorption and emission efficiency by taking energy from the molecule and storing it into nonradiative modes, enhances the absorption by increasing the local field and enhances the fluorescence by emitting efficiently the energy transfered from the emitting state to a radiative electromagnetic resonance of the particle. The present paper studies how the interplay of these effects modifies fluorescence intensity and the rate of photo-chemical reactions. (Author)
