The emission of light from a material when an electrical current or electrical field is applied to it.
Compound of 'electro-' and 'luminescence' (Latin 'luminescere' meaning to light up). The term emerged in the early 20th century as scientists discovered this phenomenon.
Electroluminescence is how LED lights work—electricity excites atoms in special materials, and when they relax they release energy as visible light, which is why LEDs are so efficient and why your phone screen glows.
