lu·mi·nes·cence

 (lo͞o′mə-nĕs′əns)
n.
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.

luminescence

(ˌluːmɪˈnɛsəns)
n
(General Physics) physics
a. the emission of light at low temperatures by any process other than incandescence, such as phosphorescence or chemiluminescence
b. the light emitted by such a process
[C19: from Latin lūmen light]
ˌlumiˈnescent adj

lu•mi•nes•cence

(ˌlu məˈnɛs əns)

n.
1. the emission of light not caused by incandescence and occurring at a temperature below that of incandescent bodies.
2. the light produced by such an emission.
[1885–90; < Latin lūmin- light + -escence]
lu`mi•nes′cent, adj.

lu·mi·nes·cence

(lo͞o′mə-nĕs′əns)
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.

luminescence

Light emission from a substance caused by an effect other than heat. Fluorescence and phosphorescence are forms of luminescence.
