A new model for the vibronic problem of luminescence of 3d3 impurity ions in the cubic environment is proposed. The approach developed is based on the numerical quantum-mechanical solution of the dynamic pseudo Jahn-Teller vibronic problem for the excited states. Spin-orbit splitting of 4t2 term and its mixing with 2E as well as the vibronic interaction with the full-symmetric local mode is taken into account resulting in the, vibronic problem and adiabatic problems. The band shape of the luminescence and the temperature dependence of the life-time decay emission are evaluated for Cr3+ ions in CdIn2S4:Cr single crystals. The proposed model provides a very good explanation of the experimental data. |
