Web1.3.2 Electroluminescence. Electroluminescence (EL) is an optical process that leads to the generation of photons as a result of the radiative recombination of holes and electrons during the passage of an electric current through a material. EL is broadly classified into two types: (1) low-field EL, wherein the injection of minority charge ...
