Optical Glass with γ-Ga2O3 Nanocrystals for UV-C Radiation Visualization

Glass meeting the GOST requirements concerning stria-free category-1 optical glass was produced in the system Me 2 O–Ga 2 O 3 –GeO 2 –SiO 2 (Me = Li, Na). The subsequent heat treatment results in the precipitation of γ-Ga 2 O 3 nanocrystals in it and triggering of luminescence excited by only UV rad...

Zusammenfassung:Glass meeting the GOST requirements concerning stria-free category-1 optical glass was produced in the system Me 2 O–Ga 2 O 3 –GeO 2 –SiO 2 (Me = Li, Na). The subsequent heat treatment results in the precipitation of γ-Ga 2 O 3 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.
