Abstract

Since the discovery of electroluminescence in anthracene single crystal in the mid 1960s, tremendous progress has been made in the performance, lifetime, stability, efficiency, as well as fabrication methods in organic electroluminescent (OEL) devices. Devices are now designed and fabricated from multilayered structures to control charge injection, transport, recombination, energy transport, and color of the devices emission. These devices that are on the order of 2000 A are now fabricated by vacuum evaporation techniques and lend themselves to high-resolution multicolored dot matrices with remarkable properties.
