Infrared (IR) Storage Phosphor SrS:Eu,Sm
More efficient and brighter than IRSPG, but more sensitive to water. Keep dry phosphor away from water. Can be mixed with non-aqueuos varnish, clear coats, atc.
700-1500nm Excitation
Orange Emission at 600nm

Phosphor must be charged with light before use. The shorter the wavelength, the faster the charging since shorter wavelengths contain higher photon energy.
Infrared light will release the charged phosphor resulting in emission of visible orange light. Once phosphor has released its energy, it must be charged again.
