P‐183: Ag:WO₃ Cermet as a Stable Cathode with Low and Tunable Reflectance for Top‐Emission OLED

Abstract

We present a new cermet cathode Ag:WO3 for top-emission OLEDs. The silver nano-particles in the layer lead to a tunable plasmonic resonance from 500 to 800 nm which limits ambient light reflection. Furthermore, the introduction of WO3 in the cathode improves the lifetime of the device.
