【Abstract】 The nonlinear optical response characteristics of Au、Ag and Cu particled composite films have been studied.It is shown that near the surface plasmon resonance,the optical nonlinearities can be enormously enhanced.By tuning the structrue parameters of the composite films which are formed by coated particles with metallic cores and nonlinear dielectric shells,the obvious nonlinear optical response characteristics can be obtained.更多还原
