Enhancing Light Outcoupling in OLEDs by Integration of Scattering Electrodes

Organic Light-Emitting Devices Limited outcoupling efficiencies are still a big problem in organic light-emitting devices. In article number Klaus Meerholz, and co-workers show a novel and general approach for the enhancement of the outcoupling efficiency: the integration of a scattering bottom electrode by using a three-step process including electro-spray deposition. The integration into devices yields in a significantly increased external quantum efficiency.
