SERS signals at the anti Stokes side of the excitation laser in extremely high local optical fields of silver and gold nanoclusters

Abstract

Surface-enhanced anti-Stokes Raman scattering from pumped excited vibrational levels and surface-enhanced hyper Raman scattering show a quadratic dependence on the excitation intensity and are discussed as incoherent two-photon excited Raman processes performed in strongly enhanced local optical fields of silver- or gold nanoclusters, where both effects can experience very similar electromagnetic enhancement conditions.
