ScholarBank@NUS Repository. https://doi.org/10.1117/12.451988||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.||Source Title:||Proceedings of SPIE - The International Society for Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/98880||ISSN:||0277786X||DOI:||10.1117/12.451988|
