Single particle spectroscopy studies on plasmon coupling enhanced two-photon photoluminescence and photo-thermal responses
surface plasmon resonance, which arises from collective oscillation of conduction band electrons induced by light radiations. Plasmon resonance can greatly modify the optical properties of nearby chromophores by enhancing their excitation efficiency, radiative and non-radiative decay rates [1, 2]. A...
