luminescence

 [lu″mĭ-nes´ens]
the property of giving off light without a corresponding degree of heat.

lu·mi·nes·cence

(lū'mi-nes'ents),
Emission of light from a body as a result of a chemical reaction. See: bioluminescence.
[L. lumen, light]

luminescence

/lu·mi·nes·cence/ (loo″mĭ-nes´ens) the property of giving off light without a corresponding degree of heat.

luminescence

(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.

Etymology: L, lumen, light, escens, beginning
1 the emission of light by a material after excitation by some stimulus.
2 the emission of light by intensifying-screen phosphors after x-ray interaction. See also thermoluminescent dosimetry.

(lū'mi-nes'ĕns)
Emission of light from a body as a result of a chemical reaction.
[L. lumen, light]

luminescence

the production of light by living organisms that is brought about by the oxidation of the protein luciferin. The reaction requires ATP and is catalysed by LUCIFERASE. See also BIOLUMINESCENCE.

luminescence

Emission of light by certain substances resulting from the absorption of energy (e.g. from electrical fields, chemical reaction, or other light), which is not due to a rise in temperature (unlike incandescence). The emitted radiation is characteristic of the particular substance. When the light emitted is due to exposure to a source of light the process is usually called photoluminescence. When the light emitted is due to either a high-frequency discharge through a gas, or to an electric field through certain solids such as phosphor which is used in fluorescent lamps, television picture tubes, etc., it is called electroluminescence. See bioluminescence; fluorescence; incandescence; fluorescent lamp; phosphorescence.
