Paper Abstract

The influence of hydrostatic densification of the parameters of the 3.15-eV luminescence and on the efficiency of photocoloration of germanosilicate glass is investigated. A four-fold decrease of the luminescence intensity under excitation at both 5 eV and 3.7 eV is revealed after 19% densification of the glass. A mechanism of relaxation of excitation of germanium oxygen-deficient centers is proposed based on the model of bistable oxygen vacancy. This mechanism explains the high sensitivity of the 3.15-eV luminescence to strain and temperature quenching.
