Electroluminescence

 

The light produced by some materials -mainly semiconductors- when exposed to an electric field. In this process, the electric field excites electrons in the material, which then emit the excess energy in the form of photons. Light-emitting diodes (leds) are the most well known example of EL.

Light is emitted in response to an applied electric current.
