Abstract

The invention relates to an organic light-emitting device comprising an organic stack of layers between two electrodes. The organic stack of layers comprises a first light-emitting layer and the first light-emitting layer comprises an emitter material adapted to generate electromagnetic radiation during operation of the device. Taken together, the transition dipole moments of the radiation generating transition of the molecules of the emitter material have an anisotropic orientation inside the first light-emitting layer, and it applies that <cos2θ> is less than ⅓, where θ is the angle between the respective transition dipole moment of the radiation generating transition of the molecules of the emitter material and a layer normal of the first light-emitting layer.
