Abstract:
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.
