Indium Tin Oxide Alternatives-High Work Function Transparent Conducting Oxides as Anodes for Organic Light-Emitting Diodes

Abstract

High electrical conductivity, outstanding optical transparency, and work functions considerably greater than that of commercial indium tin oxide (ITO) organic light‐emitting devices (OLEDs) have been obtained with non‐ITO anodes. The Figure shows the crosslinked form of triarylamine (TAA), which is spin‐coated on top of the anode to improve cohesion and charge injection efficiency.
