LUMINESCENT MATERIAL AND LIGHT-EMITTING DEVICE CONTAINING SAID LUMINESCENT MATERIAL |
摘要 |
FIELD: lighting.SUBSTANCE: invention can be used in making light-emitting devices emitting ultraviolet radiation. Luminescent material has chemical formula (YLu)LiSiO:Ln, where Ln is a trivalent rare-earth metal, chosen from Pr, Nd or mixtures thereof; 0.0 ≤ x ≤ 1.0. Luminescent material has a maximum emission of short-wave ultraviolet radiation - 200-280 nm when excited with radiation in ultraviolet spectral range. Light-emitting device has a discharge lamp equipped with a discharge vessel filled with gas, supporting discharge. At least part of wall of vessel is coated with said luminescent material.EFFECT: invention provides improved bactericidal effect.7 cl, 10 dwg, 4 ex |
