Abstract An alkali halide crystal with a high concentration of F-centers is considered. If some of these F-centers are ionized into anion vacancies (a-centers) released electrons can be trapped by other F-centers to form F′-centers. It is shown that for each original concentration of F-centers there is a certain concentration of F′-centers for which the random potential fluctuations due to negatively charged F′-centers and positively charged a-centers have enough amplitude to create Anderson localization condition in the system of F-, F′- and a-centers.
