Abstract

The functional layer encompasses ~15 nm thick Zinc Oxide nanoparticles (ZnO NPs) in a polyethylenimine ethoxylated (PEIE) matrix. PEIE acts as a surface modifier on ZnO NPs and also interlinks the individual ZnO NPs resulting in enhanced electron injection and transport. Owing to the deep valence band energy state of the ZnO NPs, the hole mobility is reduced significantly. The optimized light outcoupling in the OLED using the functional layer is achieved with the combination of optical light outcoupling simulation and thickness optimization by spin coating. The outcome of these optimizations is a solution processable high efficient, low-cost OLED.
