LUMINESCENT GLASS Russian patent published in 2015 - IPC C09K11/78 C09K11/79 C03C4/12 C03C3/95 C03C3/102

Abstract RU 2553879 C2

FIELD: physics, optics.

SUBSTANCE: invention relates to composition of luminescent glasses and can be used in laser systems as active media of up-conversion lasers with diode pumping which convert IR radiation into visible band, particularly, into spectrum green band. Luminescent glass comprises the following components, mol %: SiO₂ - 44.0-48.5; GeO₂ - 1.5-5.5; PbO - 35.0-39.5; PbF₂ - 10.5-14.0 and Er₂O₃ - 0.5-1.0. To get luminescent glass required is synthesis temperature of 900±50°C which notably simplified the process.

EFFECT: high brightness, luminescence without special teat treatment.
