Abstract

We describe a fundamental observation in Metal-Enhanced Fluorescence (MEF), which has become a leading technology in the life sciences today, namely, how the lifetime of fluorophores near-to metallic plasmon-supporting silver islands/nanoparticles, modulates as a function of excitation power irradiance. This finding is in stark contrast to that observed in classical far-field fluorescence spectroscopy, where excitation power does not influence fluorophore radiative decay/lifetime.
