phos·phor

(fos'fŏr),
1. A chemical substance that transforms incident electromagnetic or radiation energy into light, as in scintillation radioactivity determinations or radiographic intensifying screens or image amplifiers.
2. Any substance capable of exhibiting phosphorescence.
[G. phōs, light, + phoros, bearing]

phosphor

(fos′fŏr, ′for″) [Fr. phosphore, fr L. phosphorus, morning star, fr Gr. phōsphoros, light-bringer]
A substance that in radiographic intensifying screens, fluoroscopic image intensifiers, or other image receptors converts photons of ionizing radiation into light, thereby amplifying the image.

rare-earth phosphor

An element such as yttrium, gadolinium, or lanthanum, used for ultra-high-speed radiographic intensification screens.
