India, April 20 -- What Is Electroluminescence?

Discovered by Captain Henry Joseph Round in 1907, electroluminescence is the emission of light by a material when subjected to an electric current or a strong electric field.

Electroluminescence is a result of the movement of electrons in a material. When an electric current is applied, electrons are forced to move through the material. Electroluminescence is a very efficient way to produce light. Unlike incandescent lamps, which produce light by heating a filament, electroluminescent devices do not waste energy as heat. This makes them a more energy-efficient lighting source.
