ABSTRACT
This chapter introduces basic principles and materials of polymer light-emitting diodes (PLEDs). Such devices transform electricity from conjugated polymers into light. The chapter begins with the view of the architecture and fabrications of PLEDs followed by description of devices physics including elementary microscopic processes, carriers transport, electrical characteristics, Fowler–Nordheim tunneling in conjugated polymer metal–insulator–metal (MIM) diodes, and approaches to improve carrier injection. Different materials used for fabrication of PLEDs are highlighted and accurate measurement of PLEDs device parameters is described in this chapter.
