PHOTOCHROMIC LUMINESCENT GLASS Russian patent published in 2016 - IPC C03C3/15

Abstract RU 2583967 C1

FIELD: physics.

SUBSTANCE: invention relates to materials for solid-state indicators of UV radiation. Photochromic luminescent glass contains europium oxide Eu₂O₃ in concentration of 0.43-0.49 % (wt) and lithium tetraborate Li₂B₄O₇ (balance). Glass intensely luminesces when exposed to ultraviolet (UV) radiation and almost instantly changes colour when intensity of UV radiation changes. Glass can be used in simple indicators near and middle UV-range, as well as in selection of light sources.

EFFECT: technical result of invention is creation of photochromic luminescent glass having bright colour and enables to determine presence and assess intensity of UV radiation.
