- the emission of light not caused by incandescence and occurring at a temperature below that of incandescent bodies.
- the light produced by such an emission.

Either the mycelium alone or the fruiting body alone, or both, may be luminescent.
Such bodies we speak of as luminescent, and in this category belong all luminous animals.
- the emission of light at low temperatures by any process other than incandescence, such as phosphorescence or chemiluminescence
- the light emitted by such a process
Word Origin for luminescence
Fluorescence and Phosphorescence -- Prof. E. Wiedmann has made a new study of these phenomena. He proposes the general name luminescence for evolutions of light which do not depend on the temperature of the substance concerned. ["Photographic News," April 20, 1888]
- The emission of light that does not derive energy from the temperature of the emitting body, as in fluorescence and bioluminescence.
- The light so emitted.
- The emission of light as a result of the excitation of atoms by energy other than heat. Bioluminescence, fluorescence, and phosphorescence are examples of luminescence that can be produced by biological or chemical processes.
- The light produced in this way.
