  1. Electroluminescence ( EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field.

  2. Electroluminescence (EL) is an optical and electrical phenomenon where a material emits light in response to an electric current passed through it, or to a strong electric field. The term "electroluminescent display" describes displays that use neither LED nor OLED devices, that instead use traditional electroluminescent materials.

  4. Electroluminescence. The inner workings of an LED, showing circuit (top) and band diagram (bottom) The p–n junction in any direct band gap material emits light when electric current flows through it. This is electroluminescence. Electrons cross from the n-region and recombine with the holes existing in the p-region.

  5. ECL is usually observed during application of potential (several volts) to electrodes of electrochemical cell that contains solution of luminescent species ( polycyclic aromatic hydrocarbons, metal complexes, quantum dots or nanoparticles [4]) in aprotic organic solvent (ECL composition).

    An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric

  7. In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gap of the semiconductors used.
