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. n Furthermore, the invention also relates to a method for producing such a component. |
