摘要：

The third-order nonlinearity susceptibility is obtained as a function of wavelength for ZnS/CdSe/ZnS structure. Numerical calculations show that the nonlinear susceptibility of this structure depends on parameters such as structure size, relaxation time and pump photon energy. The intensity and position of third-order nonlinear susceptibility peaks depend on shell thicknesses; smaller thicknesses have peak susceptibility at shorter wavelength.
