LUMINESCENT SUBSTANCE Russian patent published in 2015 - IPC C09K11/68 C09K11/55 C09K11/78 

FIELD: physics, optics.

SUBSTANCE: invention relates to quantum electronics materials and can be used as active media for low-threshold optically pumped infrared solid-state lasers, in devices for displaying sign, graphic and television information and as scintillators. The luminescent substance has the composition Li₃BaCaGd_3-xNd_x(MoO₄)₈, where 0.05≤x≤0.13, and contains the following, with respect to oxides, wt %: Li₂O 2.30-2.38, BaO 7.87-7.96, CaO 2.88-2.95, Gd₂O₃ 27.89-28.06, Nd₂O₃ 0.26-0.67, MoO₃ - the balance.

EFFECT: luminescence intensity at the length of the electron transition ⁴F_3/2→⁴I_11/2 of a Nd³⁺ ion is 1,14-1,63 arbitrary units.
