Optical Outcoupling Enhancement in Organic Light-Emitting Diodes: Highly Conductive Polymer as a Low-Index Layer on Microstructured ITO Electrodes

A highly conductive polymer layer coated on a microstructured indium tin oxide (ITO) electrode is proposed as a simple way to enhance outcoupling in organic light‐emitting diodes. The relatively low refractive index of the conductive polymer provides an index contrast between the organic and ITO lay...

Zusammenfassung:A highly conductive polymer layer coated on a microstructured indium tin oxide (ITO) electrode is proposed as a simple way to enhance outcoupling in organic light‐emitting diodes. The relatively low refractive index of the conductive polymer provides an index contrast between the organic and ITO layers so that structuring of ITO electrodes can result in a significant optical effect.
