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]
Potassium fluorosilicate is a chemical compound with the chemical formula K 2 [SiF 6].. When doped with potassium hexafluoromanganate(IV) (K 2 [MnF 6], with Mn 4+) it forms a narrow band red producing phosphor, (often abbreviated PSF or KSF), of economic interest due to its applicability in LED lighting and displays.
In these applications, the phosphor is directly added to the plastic used to mold the toys, or mixed with a binder for use as paints. ZnS:Cu phosphor is used in glow-in-the-dark cosmetic creams frequently used for Halloween make-ups. Generally, the persistence of the phosphor increases as the wavelength increases.

Phosphor thermometry is an optical method for surface temperature measurement. The method exploits luminescence emitted by phosphor material. Phosphors are fine white or pastel-colored inorganic powders which may be stimulated by any of a variety of means to luminesce, i.e. emit light.
