Abstract

Glass meeting the GOST requirements concerning stria-free category-1 optical glass was produced in the system Me2O–Ga2O3–GeO2–SiO2 (Me = Li, Na). The subsequent heat treatment results in the precipitation of γ-Ga2O3 nanocrystals in it and triggering of luminescence excited by only UV radiation in the solar-blind range. The integral visible-light transmission and luminescence intensity of the developed material are comparable with these characteristics of glass-crystalline samples for which the glass was obtained by the melt quenching method.
