 (fŏs′fə-rĕs′əns)
n.
1. Persistent emission of light following exposure to and removal of incident radiation.
2. Emission of light without appreciable heat, as from chemiluminescence of phosphorus or bioluminescence of living organisms.

phosphorescence

(ˌfɒsfəˈrɛsəns)
n
1. (General Physics) physics
a. a fluorescence that persists after the bombarding radiation producing it has stopped
b. a fluorescence for which the average lifetime of the excited atoms is greater than 10–8 seconds
2. (General Physics) the light emitted in phosphorescence
3. (Chemistry) the emission of light during a chemical reaction, such as bioluminescence, in which insufficient heat is evolved to cause fluorescence. Compare fluorescence

phos•pho•res•cence

(ˌfɒs fəˈrɛs əns)

n.
1. the property of being luminous at temperatures below incandescence, as from slow oxidation or after exposure to light or other radiation.
2. a luminous appearance resulting from this.
3. any luminous radiation emitted from a substance after the removal of the exciting agent.

phos·pho·res·cence

(fŏs′fə-rĕs′əns)
1. The giving off of light by a substance as a result of having absorbed energy from a form of electromagnetic radiation, such as visible light or x-rays. Unlike fluorescence, phosphorescence continues for a short while after the source of radiation is removed. Compare fluorescence.
2. The light produced in this way.

phosphorescence

The emission of light by an object, and the persistence of this emission over long periods, following irradiation by light or other forms of radiation.
