Phosphorescence, emission of light from a substance exposed to radiation and
persisting as an afterglow after the exciting radiation has been removed.
In fluorescence, an object absorbs and releases lower energy light almost
simultaneously, but in phosphorescence, the release of light is delayed.
Persistent emission of light following exposure to and removal of incident
radiation. 2. Emission of light without appreciable heat, as from
chemiluminescence of ...
