flu|o|res|cence «FLOO uh REHS uhns», noun.
1. a giving off of light by a substance exposed to X rays, ultraviolet rays, or certain other rays, which continues only as long as exposure to these rays continues. The wave length of the radiation emitted is greater than that of the radiation absorbed.
2. the property of a substance that causes this. It is an ability to transform radiation so as to emit rays of a different wave length or color.
3. the light given off in this way.See also phosphorescence (Cf.phosphorescence).
[< fluor(spar) + -escence, as in phosphorescence]
