- Abstract
- The light scattering layer was fabricated by dry etching process with nano-patterned metal masks. The planarization layer using a high refractive index material and an organic light emitting diode has been fabricated on the planarization layer. The device with the scattering layer showed 40 % enhanced external quantum efficiency compared with a control device without the light scattering layer.
