List of light sources

[and artificial processes that emit light. This article focuses on sources that produce wavelengths from about 390 to 700 nanometers called visible light.

Electric discharge


Main article: Incandescence


Main article: Combustion



Nuclear and high-energy particle

Main article: Nuclear physics
Main article: Particle physics

Celestial and atmospheric

Nebula and stars
Starry sky, the Milky Way, and a shooting star
Main article: Astronomical object


Main article: Luminescence

Luminescence is emission of light by a substance not resulting from heat.


Main article: Chemiluminescence

Chemiluminescence is light resulting from a chemical reaction.


Main article: Bioluminescence

Bioluminescence is light resulting from biochemical reaction by a living organism.


Electrochemiluminescence is light resulting from electrochemical reaction.


Main article: Crystalloluminescence

Crystalloluminescence is light produced during crystallization.


Main article: Electroluminescence

Electroluminescence is light resulting of an electric current passed through a substance.


Main article: Cathodoluminescence

Cathodoluminescence is light resulting from a luminescent material being struck by the electrons.


Main article: Luminescence

Mechanoluminescence is light resulting from a mechanical action on a solid.

Triboluminescence, a type of mechanoluminescence, is light generated when bonds in a material are broken when that material is scratched, crushed, or rubbed.

Fractoluminescence, a type of mechanoluminescence, is light generated when bonds in certain crystals are broken by fractures.

Piezoluminescence, a type of mechanoluminescence, is light produced by the action of pressure on certain solids.

Sonoluminescence, a type of mechanoluminescence, is light resulting from imploding bubbles in a liquid when excited by sound.


Main article: Photoluminescence

Photoluminescence is light resulting from absorption of photons.

Fluorescence, a type of photoluminescence, is the emission of light by a substance that has absorbed light or other electromagnetic radiation.

Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs.


Main article: Radioluminescence

Radioluminescence is light resulting from bombardment by ionizing radiation.


Main article: Thermoluminescence

Thermoluminescence is light from the re-emission of absorbed energy when a substance is heated.


Cryoluminescence is the emission of light when an object is cooled.
