Paper Abstract

Energy transfer between fluorescent dye molecules and small silver particles can improve the apparent fluorescence quantum yield for the dye, provided that the silver particles are of a suitable size and form to amplify the total absorption and fluorescence. This mechanism provides a possibility for extending the range of dyes which could be used in fluorescent collectors to longer wavelengths, by increasing the quantum yield and long-term stability of dyes absorbing in the NIR. Composite material models of the optical characteristics and measurements of the absorption, fluorescence and fluorescence lifetime are used to investigate this effect.
