Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from heat (incandescence), from a chemical reaction (chemiluminescence), sound (sonoluminescence), or ...
production of light by the flow of electrons, as within certain crystals. Electroluminescence is one of the few instances in which a direct ... [3 related articles]
emission of optical radiation in excess of that radiation due to normal thermal emission resulting from the application of electrical energy NOTE - One example is the photon emission resulting from electron-hole recombination in a PN junction such as in a light emitting diode.luminescence caused by the action of an electric field in a gas or in a solid material (Destriau effect, or radiative recombination as in light-emitting diodes)
electroluminescence, electroluminescent The emission of light by something such as a gas or phosphor resulting from a high-frequency electric discharge.
luminescence produced by the activation of a dielectric phosphor by an alternating current.
