LUMINESCENT GLASS Russian patent published in 2013 - IPC C03C3/95 C03C3/06 

FIELD: chemistry.

SUBSTANCE: invention relates to legated glasses, which can be used as anti-Stokes visualisers of IR-radiation with λ≈0.89-0.99 mcm, active medium of amplifiers and laser converters, functioning in band of anti-Stokes luminescence, as well as for visual control of laser IR-radiation power. Luminescent glass contains silicon dioxide, ytterbium oxide Yb₂O₃, erbium oxide Er₂O₃ and rubidium oxide Rb₂O with the following component ratio, wt %: SiO₂ - 85.8-92.7; Yb₂O₃ - 4.9-9.8; Er₂O₃ - 0.8-2.4; Rb₂O - 1.6-2.4.

EFFECT: creation of glass with high effectiveness of anti-Stokes luminescence in case of excitation in spectral region with λ≈0,89-0,99 mcm, and high section of amplification in main band of anti-stokes luminescence.
