中文摘要:

      将激励光与液相金纳米粒子相互作用的运动方程表达为朗之万方程,对金纳米粒子的共振散射、2/3分频共振散射和2倍频共振散射进行了分析,较好地解释了液相金纳米粒子产生的一些非线性散射现象.

英文摘要:

      The interaction motion equation between the stimulated light and Au nanoparticle in solution has been transffered into a Langevin equation. The resonance scattering, 2/3 fraction frequency resonanance scattering and 2ω\-0 frequency resorance scattering have been analysed. Some nonlinear scattering phenomena for Au nanoparticle have been explained also by the work.
