摘要：

We have investigated third-harmonic generation (THG) of spherical quantum dots (QDs) with inversely quadratic Herman (IQH) potential under the influence of Al-concentration, temperature and hydrostatic pressure in the reported work. The Schro center dot dinger equation which from the definition is solved using the Nikiforov-Uvarov (N-U) method, and then the wave function and energy level interval are derived. The compact density matrix and iterative methods are used to calculate the nonlinear optical THG. The numerical results show that under different constraint parameters, the resonance peak of THG moves to high energy or low energy, that is, redshift or blueshift. In addition, the peak of THG will increase or decrease with the change of parameters.
