2 - Transparent conducting thin films for OLEDs

Abstract

In an organic light-emitting diode, at least one of the electrodes has to be transparent or semitransparent. Transparent conducting thin films for organic light-emitting diodes (OLEDs) are of great importance for designing high performance OLEDs. In this chapter, three major transparent/semitransparent thin films, i.e. transparent conducting oxide thin films, metal thin films and carbon based conductive thin films, as transparent electrodes in OLEDs will be discussed. In particular, the focus will be on the optimization of desired work function of these thin films.
