Solution-processed organic light-emitting devices

Abstract

Recent progresses on materials and device structures for solutionprocessed organic light-emitting devices (OLEDs) are discussed. Several solution-processable materials such as fluorescent oligomer, phosphorescent dendrimer, lithium complex, zinc oxide, and polyvinylpyridine are designed and synthesized for achieving multilayer structure. The successful fabrication of solution-processed white phosphorescent OLEDs and tandem OLEDs will pave the way toward printable, low-cost, and large-area solid-state lighting application.
