Preparation and Optical Properties of Au/BaTiO3 Nanoparticle Composite Thin Films

Abstract

Abstract: High doping level of Au nanoparticles was successfully incorporated into sol-gel derived amorphous BaTiO₃ thin films, and the optical properties of samples
were studied. The characteristics of samples were investigated by using XRD, TEM, absorption spectra, and OKE(Optical Kerr Effect) techniques. Red shift of SPR
(surface plasma resonance) absorption along with the increase of treat temperature was observed by absorption spectra. Films exhibited a larger third nonlinear
susceptibility χ⁽³⁾ and superfast response time in the nonlinear optical test.

Key words: metal nanoparticles, sol-gel, surface plasma resonance, nonlinearities
