Parametric Relative Properties of Thirdorder Nonlinear Optical Susceptibilities in a Zns/CdSe/ZnS CoreShellShell Spherical Quantum Dot
Under the effectivemass approximation,the analytic expression for Selffocusing effect in ZnS/CdSe/ZnS coreshellshell spherical quantum dots was derived by using the density matrix method. The numerical caculations were perforomed on the thirdorder susceptibilities as a function of the size of quantum dots and the frequency of the incident light were analyzed.The numerical results reveal that the thirdorder susceptibilities will increase with the increase of the quantum dot size, and position of the peak will red shifts. The conclusions provide a theoretical basis for experimental research and practical applications, and for research and improvement of photoelectric device with references.
