    • In the case of static charge transfer, electrons with sufficient energy to tunnel through the barrier to the adsorbate resonant state (here, in Fe 3O4 leaves) reside in this state for a long time and build up enough charge to prohibit further electron transfer from the gold particle. In our case, however, the most important component of the interface decay channel is the dynamic charge transfer,[28] when electrons with energies sufficient to overcome the barrier reside in the adsorbate state only temporarily, and gradually tunnel back to the gold particle. These electrons are out of phase with the collective electronic excitation (SPR)ofgold and therefore contribute significantly to its damping for further details see Ref, 28

    • We note that although it is tempting to rationalize band broadening by the formation of an effective/continuous iron oxide shell around the Au core, this simplified model does not account for the experimentally observed degree of broadening. Correct explanation must incorporate interface-decay- channel arguments discussed in the main text
