Abstract

In this paper, we present the results of the theoretical evaluation of the vibronic linear coupling constants for the V3+ doped in Li(Al,Ga)O2 crystal. In the case of a tetrahedral complexs V3+: Li(Al,Ga)O2 the interaction with full symmetric A1, tetragonal E and two trigonal vibrations T2 (1) and T2 (2) are considered. The liniar vibronic coupling constants are numerically calculated for each case of the Jahn-Teller interactions and all considered types such interaction are expected to give information on the new peculiarities of the absorption and emission bands, as well as of non-radiative transitions between the electronic states of impurity ions..

Keywords
