When molecules are adsorbed on silver island films, their fluorescent lifetimes are found to be shortened by about three orders of magnitude and their decay is found to be non— exponential in time. This behavior is a result of the electromagnetic interaction between the molecules and the silver islands. The emission process of the molecule—island system can be quite efficient, and the increased radiative rate can lead to an improved effective quantum yield for adsorbates on silver-island films. Recently, much interest has been focused on the optical properties of molecules near rough metal surfaces.
