Electroluminescence with organic compounds

Some fundamental aspects of basic principles and applications of electroluminescence, based on organic low molecular weight compounds and polymeric compounds will be presented. The basic working principles and the basic construction of electroluminescent devices are described. Some factors affecting the efficiencies and lifetime or organic electroluminescent devices are reviewed, describing recent developments in dye‐based organic hetero‐junction and polymer systems. The distinctive advantages of these organic LEDs are high efficiency of all colors and potential ease of fabrication, offering the possibility of applications in flat‐panel displays. No attempt is made in the present article to review the whole field, but instead this interesting field is described by focusing on a few selected topics, and by describing few representative results.
