Organic light-emitting diode configured such that light is efficiently decoupled from plasmon modes of a metal electrode

摘要

In at least one embodiment of the organic light-emitting diode (10), the latter comprises a first electrode (1), which is formed with a metal, and a second electrode (2). In addition, the organic light-emitting diode (10) contains an organic layer sequence (3) located between the first electrode (1) and the second electrode (2). Moreover, the organic light-emitting diode (10) comprises a radiation-transmissive index layer (4), which is located on an outer side (11) of the first electrode (1) remote from the organic layer sequence (3). The average refractive index of the index layer (4) is greater than or equal to the average refractive index of the organic layer sequence (3). At least some of the electromagnetic plasmon radiation (P) generated by the organic light-emitting diode (10) passes through the index layer (4).
