ORGANIC LIGHT-EMITTING DIODE

摘要

In at least one embodiment of the organic light-emitting diode (10), the organic light-emitting diode comprises a first electrode (1), which is composed of a metal, and a second electrode (2). Furthermore, the organic light-emitting diode (10) contains a sequence (3) of organic layers that is located between the first (1) and the second electrode (2). In addition, the organic light-emitting diode (10) comprises an index layer (4) that is transparent to radiation and that is located on an outer face (11) of the first electrode (1) facing away from the sequence (3) of organic layers. An average index of refraction of the index layer (4) is greater than or equal to an average index of refraction of the sequence (3) of organic layers. At least part of the electromagnetic plasmon radiation (P) produced by the organic light-emitting diode (10) passes through the index layer (4).
