(C, D) Calculated quantum yield qa, excitation rate γexc and fluorescence emission rate γem normalized with free-space values as a function of fluorophore-metal separation for 80 nm Au NPs (C) and Au NPs with various diameters (D). Solid curves: MMP calculations, dashed curves: dipole approximation. Reprinted figures with permission from [Anger, P.; Bharadwaj, P.; Novotny, L.
