[fos-fuh-res-uhns]
noun
1.
the property of being luminous at temperatures below incandescence, as from slow oxidation in the case of phosphorus or after exposure to light or other radiation.
2.
a luminous appearance resulting from this.
3.

phosphorescence   (fŏs'fə-rěs'əns)  Pronunciation Key 
  1. The emission 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. Glow-in-the-dark products are phosphorescent. Compare fluorescence.

  2. The light produced in this way.
