The experimental results show that the third-order nonlinear optical susceptibility of the composite films strongly depends on metal particle size and matrix refractive index. 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:||Journal of Nonlinear Optical Physics and Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/98881||ISSN:||02188635||DOI:||10.1142/S0218863503001298|
