Abstract
The third-order nonlinear optical response of Au nanocrystals embedded in BaTiO3 and ZrO2 matrices were investigated by off-resonance femtosecond optical Kerr effect. The nonlinearity of composite films show an enhancement comparing with the pristine matrices films, which is Au particle size and matrices refractive index dependence. A calculation based on Lorenz-Mie scattering theory was performed to explain the experimental results. Additionally, optimization of nonlinearity was obtained by considering the particle size and matrices refractive index.
