Paper Abstract

Second harmonic generation (SHG) behaviors will be presented for NLO polymer/Au nanoparticle hybrid structures. The NLO polymer is the material rich in the nonlinear susceptibilities and it is suitable for coating on the metal surfaces. The Au nanoparticles themselves exhibit enhanced SHG effects at localized surface plasmon (LSP) resonances. Our experimental results demonstrated that the Au nanoparticles coated with the NLO polymer emitted more than one magnitude higher SHG signals than the bare Au nanoparticles. The enhanced nonlinearities due to the NLO polymers were explained in terms of not only electromagnetic mechanism but also molecule-to-metal charge transfer mechanism.
