发明名称 Light-emitting component
摘要 The invention relates to a light-emitting component, in particular organic light-emitting diode, having an electrode and a counterelectrode and an organic region—arranged between the electrode and the counterelectrode—with a light-emitting organic region, which comprises an emission layer and a further emission layer and which, upon application of an electrical voltage to the electrode and the counterelectrode, is formed in a manner emitting light in a plurality of colour ranges in the visible spectral range, optionally through to white light, in which case the emission layer comprises a fluorescent emitter which emits light predominantly in the blue or in the blue-green spectral range; the further emission layer comprises one or a plurality of phosphorescent emitters emitting light predominantly in the non-blue spectral range; a triplet energy for an energy level of a triplet state of the fluorescent emitter in the emission layer is greater than a triplet energy for an energy level of a triplet state of the phosphorescent emitter in the further emission layer; and an at least 5% proportion of the light generated in the light-emitting organic region is formed in the visible spectral range as fluorescent light from singlet states of the fluorescent emitter in the emission layer.
