Abstract
This paper presents the results of studying the absorption, luminescence, and excitation spectra of oxygen-deficient centers (ODCs) in glasses obtained from quartz raw materials with different contents of the cristobalite phase (0–80%). With an increase in the content of the cristobalite phase, an increase in the intensity of the luminescence band corresponding to singlet-singlet transitions in the center of the oxygen vacancy type near the germanium impurity ion is observed. Differences in the short-range order of quartz glasses obtained from the initial raw materials with different contents of α-quartz and cristobalite phases are studied.
