Abstract

The photoluminescence properties of beryllium ceramic obtained by semidry molding with and without deliberately introduced alkali metal impurities are considered. It is assumed that heat treatment of samples in hydrogen and the introduction of lithium and sodium impurities in small quantities lead to the formation of additional luminescent centers increasing the intensity of photoluminescence. In contrast, large concentrations of the impurity phase suppress photoluminescence. In heterovalent replacement of Be2+ with Li+ or Na+ ions, additional oxygen vacancies are formed, in which electrons can be localized under radiation and F+ centers can be formed.
