In the system Me 2 O & mdash; Ga 2 O 3 & mdash; GeO 2 & mdash; SiO 2 < / sub> (Me = Li, Na) a glass was obtained that meets the requirements of GOST in terms of impossibility for optical glass of the first category. Subsequent heat treatment results in the release of & # 947; -Ga 2 O 3 nanocrystals in it and the initiation of luminescence, excited only by UV radiation of the solar-blind range. The integral light transmission in the visible region and the luminescence intensity of the developed material are comparable with the same characteristics of glass-crystalline samples, the glass for which was obtained by melt quenching.
