Definition
A 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 [2,3,4]. 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 semiconductor material is a chemical compound whose molecules contain carbon and hydrogen (C-H bonds). A property of carbon is that it can link with other carbon atoms to form long chains, a process called polymerization. The chains are called polymers. Artificially (synthetically) produced polymers are called plastics. Semiconductor polymers can be produced as thin films with...
