The influence of fluctuation potential on self-trapping excitons dynamics in the crystal KI

Abstract

There is an excitons self-trapping continuum model with the fluctuation potential in this article. The temperature dependence alkali halides lattice constant expression have written with the apply of quantum mechanical theory. On the example of KI crystal we made the graph of temperature dependence of the excitons self-trapping potential barrier height. Such results we interpreter by self-trapping luminescence intensity growth in alkali halides with the temperature increasing.
