Preparation and Optical Properties of Au/BaTiO_3 Nanoparticle Composite Thin Films
Source 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 x(3) and superfast response time in the nonlinear optical test.
