A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy.
Polycrystalline Mn:SrAl 12 O 19 is used as a green phosphor for plasma displays, and when doped with praseodymium or neodymium it can act as a good active laser medium. Sr 0.95 Ce 0.05 Mg 0.05 Al 11.95 O 19 is a phosphor emitting at 305 nm, with quantum efficiency of 70%. Several strontium aluminates can be prepared by the sol-gel process. [6]
The term phosphor had been used since the Middle Ages to describe minerals that glowed in the dark. One of the most famous, but not the first, was Bolognian phosphor.

A circular cut of a PSP plate. On photostimulable phosphor (PSP) plates, the phosphor layer is typically 0.1 to 0.3 mm thick. After the initial exposure by short-wavelength (typically, X-ray) electromagnetic radiation, excited electrons in the phosphor material remain 'trapped' in 'colour centres' ("F-centers") in the crystal lattice until stimulated by the second illumination.
