Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. Usually, the short persistence phosphorescent pigment takes zinc sulfide as base and copper as activator. While, for long persistence phosphorescent pigment, alkaline earth aluminate or alkaline earth silicate will be the base and rare earth ions become the activator.
