Kortov, I. Mil'man] The results of experimental and theoretical research on thermally stimulated luminescence (TSL) of dosimetric crystals based on anion-defect corundum are systematized. It is shown that all of actually observed features — the dependence of the TSL yield on the heating rate, the dependence of the temperature position of the TSL peak and its shape on the irradiation dose and the heating rate, and the drop in average activation energy within a dosimetric peak — are due to a single process: quenching of the luminescence ofF centers. Evidence is given for a relationship between quenching and the presence of oxygen vacancies of thermochemical or radiative origin. Unusual behavior of Cr3+ ions during thermoluminescence is found. It is suggested that the TSL peak in anion-defect corundum is due to a complex defect formed by oxygen vacancies in various charged states, chromium ions, and possibly the ions of other transition metals.
