Color-stable, ITO-free white organic light-emitting diodes with enhanced efficiency using solution-processed transparent electrodes and optical outcoupling layers.

Highlights: [•] Color-stable, ITO-free white OLEDs with enhanced efficiencies were demonstrated. [•] High-conductivity PEDOT:PSS was used as the transparent anode. [•] Nanoparticle-based scattering layers were used for light extraction. [•] Both can be fabricated by simple, low-temperature solution processing. [•] Such an approach simultaneously provides manufacturing, cost and efficiency advantages. [ABSTRACT FROM AUTHOR]
