    摘要: The present invention relates to a radiation-emitting device comprising a substrate, a first and a second electrode, and an emitter layer arranged between the first and the second electrode that emits light in the violet or blue spectral range. The emitter layer contains a matrix material and (relative to the matrix material) 0.1 - 5 wt % of a fluorescent radiation-emitting emitter and 1-30 wt % of a phosphorescent exciton trap. The maximum emission of the fluorescent emitter and the maximum emission of the phosphorescent exciton trap lie within the blue, violet, or ultraviolet spectral range.
