ELECTROLUMINESCENCE WITH ORGANIC-COMPOUNDS

Some fundamental aspects of basic principles and applications of elect roluminescence, based on organic low molecular weight compounds and po lymeric compounds will be presented. The basic working principles and the basic construction of electroluminescent devices are described. So me factors affecting the efficiencies and lifetime or organic electrol uminescent devices are reviewed, describing recent developments in dye -based organic heterojunction and polymer systems. The distinctive adv antages of these organic LEDs are high efficiency of all colors and po tential ease of fabrication, offering the possibility of applications in flat-panel displays. No attempt is made in the present article to r eview the whole field, but instead this interesting field is described by focusing on a few selected topics, and by describing few represent ative results.
