Fluorescence quenching in the proximity of noble metal nanoparticles has found extensive use in environmental and biological sensing over the past decade. However a complete and predictive model of quenching that is valid across nanoparticle sizes and fluorophore wavelengths remains elusive. We present a theoretical model that can predict the rates of quenching near the surface of spherical noble metal nanoparticles as a function of particle size and fluorophore wavelength.
