1. 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.
2. The light so emitted.

1. The emission of light as a result of the excitation of atoms by a source of energy other than heat. Bioluminescence, fluorescence, and phosphorescence are examples of luminescence that can be produced by biological or chemical processes.
2. The light produced in this way.
