List of light sources

Lightning

This is a list of sources of light, including both natural and artificial processes that emit light. This article focus on source of wavelengths from about 390 to 700 nanometres that called visible light , as opposed to objects such as the Moon that provide light by reflection.

Cathodoluminescence

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

Mechanoluminescence

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

• Triboluminescence

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

• Fractoluminescence

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

• Piezoluminescence

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

• Sonoluminescence

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

Photoluminescence

Photoluminescence is light resulting from absorption of photons.

• Fluorescence

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

• Phosphorescence

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

Radioluminescence

Radioluminescent

Radioluminescence is light resulting from bombardment by ionizing radiation.

Thermoluminescence

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

Cryoluminescence

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