Abstract
The observed broadening of the line shape of the emission spectra of t he luminescence centers in crystals with high electron-lattice couplin g has been explained in terms of the ion-motion spatial confinement in the lattice. For this, a simple and analytically solvable model for t he potential of the electronic energy sheets has been proposed. As an example of application the emission spectrum of BiO69-complex has been analyzed.
