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, 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
