  • 摘要:The eigenenergies and eigenfunctions of the spherical PbSe/CdSe/ZnS quantum-dot with the core-shell-shell structure and the electric dipole moment between the a 1s state (the lowest state of the system) and b 1p state (the lowest p state above the first potential) have been calculated by using the rotational wave approximation and the effective mass approximation. The optical nutation signal induced by the transition between these two energy levels has been calculated based on the optical Bloch equations. In particular, the influence of the core’s radius increasing and the CdSe …
