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

FIELD: chemistry.

SUBSTANCE: invention relates to optical materials, particularly activated glass compositions obtained by a sol-gel technique, which can be used as active components of lasers and super-luminescent emitters operating in the region of maximum spectral efficiency of photosynthesis. Said glass contains silicon, samarium, aluminium and rubidium oxides, as well as OH^- groups in the following ratios (wt %): (94.6-98.8)SiO₂, (0.5-2.2)Sm₂O₃, (0.5-2.2)Al₂O₃, (0.1-0.8)Rb₂O and (0.1-0.3)OH^-.

EFFECT: producing Sm-containing glass with weak concentration quenching of luminescence, which increases concentration of activator operating on a four-level scheme and consequently radiation energy obtained per unit volume of said glass when used as active components of lasers and super-luminescent emitters.
