    • 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.
    • 本发明涉及一种具有电极和反电极的发光部件,特别是有机发光二极管,其具有发光有机区域,该发光部件包括发光层 以及另外的发射层,并且在以可发射的光谱范围内的多个颜色范围内发射光的方式(可选地通过白光)形成对电极和反电极施加电压时,在这种情况下, 发射层包括以蓝色或蓝 - 绿光谱范围发光的荧光发射体; 所述另外的发射层包括以非蓝色光谱范围发射光的一个或多个磷光发光体; 在发射层中荧光发射体的三线态的能级的三线态能量大于在另外的发射层中的磷光发射体的三线态的能级的三线态能量; 并且在发光有机区域中产生的光的至少5%的比例作为来自发光层中的荧光发射体的单线态的荧光形成在可见光范围内。
