COMPLEX SILICATE OF RARE-EARTH ELEMENTS Russian patent published in 2025 - IPC C09K11/79 C09K11/78 C09K11/55 B82B3/00 B82Y40/00

Abstract RU 2832831 C1

FIELD: chemistry.

SUBSTANCE: invention relates to green luminophores and can be used to visualize light in the infrared range in lighting systems and visualize biological tissues. Disclosed is a new chemical compound – complex silicate of rare-earth elements of the composition Sr₂Y_8-x-yYb_yHo_xSi₆O₂₆, where 0.005 ≤ x ≤ 0.05, 0.2 ≤ y ≤ 0.3, in nanoamorphic state as up-conversion luminophore of green luminescence. New composition of the up-conversion luminophore provides high purity of luminescence along with intense green luminescence.

EFFECT: proposed invention widens the range of green luminophores used for imaging light in the infrared range.
