Definition
Light source that produces light as a result of recombination of positively charged holes and negatively charged electrons at the junction of organic, solid-state, p- and n-type planar semiconductor materials.
Solid-State Light Sources
LEDs are solid-state radiators where the light is created inside solid-state material [2–4]. The light-radiating diode versions are called light-emitting diodes or LEDs. Light-emitting diodes made of organic semiconductor material are referred to as OLEDs; they are planar light sources (Fig. 1). Organic material is a semiconductor chemical compound whose molecules contain carbon and hydrogen (C – H bonds). The name LED is commonly used for light-emitting diodes made of inorganic semiconductor material; they are quasi point light sources. A separate chapter deals with LEDs. Serious development of OLEDs only started in the mid-1990s of the last century. OLEDs can be produced to give...
