[Latin Phōsphorus, the morning star; see phosphorus.]phosphor (ˈfɒsfə) n (General Physics) a substance, such as the coating on a cathode-ray tube, capable of emitting light when irradiated with particles or electromagnetic radiation[C17: from French, ultimately from Greek phōsphoros phosphorus]phos•phor (ˈfɒs fər, -fɔr)
n. a substance that exhibits luminescence when struck by light of certain wavelengths, as by ultraviolet. [1625–35; < French phosphore < Latin Phōsphorus < Greek Phōsphóros light-bringing, the morning star =phôs light + -phoros bringing] phos·phor (fŏs′fər) A substance that can emit light after absorbing some form of radiation. The insides of television screens and fluorescent lamp tubes are coated with phosphors.
