The external quantum efficiency (EQE) of ITO-free device can be significantly enhanced by a factor of 1.8 at 1000 cd/m2. © 2012 SID.ITO-Free; OLED; Optical Out-couplingConducting polymers; Efficiency; Nanocomposites; Organic light emitting diodes (OLED); Polymer films; Transparent electrodes; Efficiency enhancement; External quantum efficiency; High conductivity; ITO free; Nano-composite scattering films; OLED; Optical extraction; Solution-processed; Nanocomposite filmsconference paper10.1002/j.2168-0159.2012.tb06095.x2-s2.0-84973353718
