An example of luminescence is fluorescence, the light that a fluorescent bulb produces.
Origin of luminescencefrom Classical Latin lumen, light + -escence
- The emission of light that does not derive energy from the temperature of the emitting body, as in phosphorescence, fluorescence, and bioluminescence. Luminescence is caused by chemical, biochemical, or crystallographic changes, the motions of subatomic particles, or radiation-induced excitation of an atomic system.
- The light so emitted.
