N2 - The enhanced and localized multiphoton excitation of rhodamine B (RhB) fluorescence near metallic silver islands is studied. The close-proximity metallic silver islands alter the radiative decay rate and excitation rate of fluorophores. The increase in fluorescence emission intensity for RhB molecules adjacent to metallic silver islands is accompanied by a reduction in lifetime. In addition to modifying a fluorophore's radiative decay, the metallic particles or colloids also increase the excitation rates by concentrating the incident light.
