Luminescence is emission of light by a substance not resulting from heat.
Chemiluminescence is light resulting from a chemical reaction.
Bioluminescence is light resulting from biochemical reaction by a living organism.
- Aequorea victoria
- Antarctic krill
- Cavitation bubbles
- Panellus stipticus
- Parchment worm
Electrochemiluminescence is light resulting from electrochemical reaction.
Crystalloluminescence is light produced during crystallization.
Electroluminescence is light resulting of an electric current passed through a substance.
- Light-emitting diodes
- Organic light-emitting diodes
- Polymer light-emitting diodes
- Light-emitting electrochemical cell
- Electroluminescent wires
- Field-induced polymer electroluminescent
Cathodoluminescence is light resulting from a luminescent material being struck by the electrons.
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 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 is light resulting from bombardment by ionizing radiation.
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.
