“…Plasmonic nanostructures (Au, Ag) exhibit localized surface plasmon resonance (SPR), the coherent oscillation of conduction electrons coupled to strong local electric fields. Landau damping of the SPR (1-100 fs) promotes excitation of energetic, or "hot", charge carriers [3,8,9], in addition to increasing light absorption, enhancing far-field light scattering, and inducing charge separation in semiconductors [3,6,[8][9][10]. Ohmic relaxation of "hot" electrons (100 fs to 1 ps) results in local thermal dissipation (100 ps to 10 ns) that can aid in activating adsorbed reactants and accelerating surface kinetics [3,9,10].…”
