    • A radiation-emitting device for emitting electromagnetic radiation which is a mixture of at least three different partial radiations of a first, a second and a third wavelength range. The radiation-emitting device here comprises a substrate; a first electrode and a second electrode, at least one first layer sequence arranged between the first and second electrodes comprising: at least one first layer with a first fluorescent emitter, which emits radiation in the first wavelength range, at least one second layer with a first phosphorescent emitter, which emits radiation in the second wavelength range; at least one second layer sequence arranged between the first and second electrodes comprising: at least one first layer with a second fluorescent emitter, which emits radiation in the first wavelength range, at least one second layer with a second phosphorescent emitter, which emits radiation in the third wavelength range, and at least one interlayer, which is free of emitter material and is arranged between the first and the second layer sequences.
    • 一种用于发射作为第一,第二和第三波长范围的至少三个不同部分辐射的混合物的电磁辐射的辐射发射装置。 这里的辐射发射器件包括衬底; 第一电极和第二电极,布置在第一和第二电极之间的至少一个第一层序列,包括:具有第一荧光发射器的至少一个第一层,其发射第一波长范围的辐射,至少一个第二层, 第一磷光发射体,其在第二波长范围内发射辐射; 布置在第一和第二电极之间的至少一个第二层序列包括:具有第二荧光发射器的至少一个第一层,其在第一波长范围内发射辐射,至少一个第二层与第二磷光发射器发射辐射, 第三波长范围和至少一个中间层,其不含发射体材料并且布置在第一和第二层序列之间。
