Luminescence[edit]

Main article: Luminescence

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

Chemiluminescence[edit]

Main article: Chemiluminescence

Chemiluminescence is light resulting from a chemical reaction.

Bioluminescence[edit]

Main article: Bioluminescence

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

Electrochemiluminescence[edit]

Electrochemiluminescence is light resulting from electrochemical reaction.

Crystalloluminescence[edit]

Main article: Crystalloluminescence

Crystalloluminescence is light produced during crystallization.

Electroluminescence[edit]

Main article: Electroluminescence

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

Cathodoluminescence[edit]

Main article: Cathodoluminescence

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

Mechanoluminescence[edit]

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.

Photoluminescence[edit]

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.

Radioluminescence[edit]

Radioluminescent
Main article: Radioluminescence

Radioluminescence is light resulting from bombardment by ionizing radiation.

Thermoluminescence[edit]

Main article: Thermoluminescence

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

Cryoluminescence[edit]

Main article: Cryoluminescence

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