    • In the quasistatic limit, the dispersion of polarizability is not affected by the particle size unless the metal dielectric permittivity is size-dependent. This is our case; see eq 7

    • To be more precise, at short distances, several MNP multipoles intervene in the molecule-to-metal energy exchange (ref 11, whereas RIm represents only the dipole contribution, which dominates at long distances. The maximum efficiency of the metal as a energy acceptor at short distances is thus slightly red-shifted with respect to the RIm peak ref 30, Although all multipoles are taken into account in our calculations, for a qualitative rationalization of our results, reference to RIm is enough
