摘要:
A radiation emitting device comprising a first electrode, which emits first charge carriers having a first charge during operation, a first charge carrier transporting layer, which comprises a fluorescent substance, a second charge carrier transporting layer, which contains a phosphorescent substance, and a second electrode, which emits second charge carriers having a second charge during operation, wherein during operation the second charge carrier transporting layer is largely free of first charge carriers.
