ABSTRACT
The field of organic light-emitting devices, for which the name “molecular lightemitting devices” might be better suited because it actually includes many inorganic active compounds [such as the highly popular tris(8-hydroxyquinolinato) aluminum], has grown immensely in the last decade. Numerous studies are published every year, many of them reporting new substances with improved emission properties, stability, and lifetimes. Moreover, displays made with polymer light-emitting devices are currently being commercialized. These devices are no longer only toys for scientists around the world; their study has evolved into a new, growing technology.
