Electroluminescence

Recent studies have been made on electroluminescence (EL) of organic compounds where light emission occurs upon application of a voltage. Since Tang reported multilayered organic EL devices in 1987, related research and development has rapidly progressed. Today, there are some which are put in practical use. Organic EL devices have characteristic features such as spontaneous emission,
low-voltage driving force, no dependence on view angles, high-speed response properties, and high brightness. They are expected to be useful as flat panel display materials.
The multilayered organic EL devices consist of a hole transport layer, electron transport layer and emitter layer and depending on the combination, either the hole transport layer or electron transport layer may serve dually as the emitter layer. Emission wavelengths are controlled by doping trace amounts of fluorescent dyes in the emitter layer. Furthermore, the polymer-type EL devices such as light-emitting polymers and polymers dispersed with low-molecular weight fluorescent compounds are being studied because of ease of processing.
