摘要： In order, in the case of an OLED, to improve the coupling-out efficiency, a top emitting electroluminescent component (100) is proposed, comprising a substrate (110), a first electrode (120) closest to the substrate, a transparent electrode (140) located at a distance from the substrate, and at least one light-emitting organic layer (130) arranged between the two electrodes. The component according to the invention is distinguished by the fact that a coupling-out layer (150) is arranged on that side of the second electrode which is remote from the at least one organic layer, said coupling-out layer comprising conversion centres (151) which partly absorb the light emitted by the at least one organic layer and emit it again with an altered frequency. In this way, directional light penetrating into the coupling-out layer is emitted again in non-directional fashion, so that a part of the light which would be captured by means of total reflection without the influence of the frequency conversion centres within the coupling-out layer can indeed leave the coupling-out layer.Furthermore, the invention also relates to a method for producing such a component.
