摘要 根据多孔硅中的量子限制效应和金属颗粒与电磁场相互作用的Mie理论及非线性光学的基本原理,提出了用于复合金属纳米颗粒多孔硅微结构的计算模型,分析了复合金属纳米颗粒多孔硅的非线性光学性质.计算了复合Ag(Au)纳米颗粒多孔硅的场增强因子,得到了在不同的金属颗粒含量时,复合体系的三阶极化率随入射光波长变化的关系,为制备具有强非线性光学效应的硅基材料及其应用提供了重要参考. The microstructure model for the computation of the porous silicon with metallic nanoparticles has been proposed and the nonlinear optical properties of this compound system has been analysed, based on the quantum confinement effect in porous silicon,the theory of interaction between metal particles and electromagnetic field and the principle of nonlinear optics. The field enhancement factor of porous silicon with Ag(Au) nanoparticles has been derived and the relation between the nonlinear susceptibility of this material and the incident wavelength in different concentration of metallic nanoparticles has been obtained.
