FIELD: luminescent compositions. SUBSTANCE: luminophore based on YO: Eu and activated by Tb or Pr has Ge, Ga, In at the following ratio of components, wt.-%: Eu 3.5-6; Tb 0.005-0.008; Pr 0.004-0.008; Ge 0.025-0.15; Ga 0.015-0.1; In 0.01-0.05, and YO- the rest. Properties: brightness is 105-110 rel. U; chromaticity coordinates: x = 0.635-0.647, y = 0.347-0.359. EFFECT: enhanced quality of luminophore. 6 ex |
