phosphor

A substance capable of luminescence, such as a fluorescent powder which absorbs ultraviolet power and reemits it as visible light; used to coat the inside of various electric-discharge lamps.

phosphor

A rare earth material used to coat the inside face of a CRT. When struck by an electron beam, the phosphor emits a visible light for a few milliseconds. In color displays, red, green and blue phosphor dots are grouped as a cluster. See screen burn and phosphorene.
