LUMINESCENT MATERIAL Russian patent published in 2018 - IPC C09K11/78 C09K11/55 C09K11/68 

FIELD: optics.

SUBSTANCE: invention relates to materials of quantum electronics, integrated optics and can be used to produce light-emitting diodes of white glow, scintillators, sensors, for displaying sign, graphic and television information. Luminescent material of composition Li₃BaSrGd_3-3xEu_3x(WO₄)₃(MoO₄)₅, where 0.017≤x≤0.05, is obtained from oxides of lithium, barium, strontium, gadolinium, europium, molybdenum and tungsten at the following ratio of the indicated components (mass%): Li₂O 1.98–2.06; BaO 6.77–6.85; SrO 4.58–4.63; Gd₂O₃ 22.98–23.16; Eu₂O₃ 0.27–0.85; WO₃ 30.73–30.79; MoO₃ – the rest being.

EFFECT: invention provides an increase in the luminescence intensity of the europium ion at the length of the electronic transition ⁵D₀→^7thF₂.
