Abstract
Pentaphosphates of the formula XP.sub.5 O.sub.14, wherein X is a rare earth metal, respond to incident ionizing radiation by emitting secondary electromagnetic radiation which may be visible or may be made visible by doping with other rare earth metal pentaphosphates or mixtures of Mn and Sb ions. The pentaphosphates of Ce and Pr respond quickly to cessation of incident radiation so that they are used to advantage in scintillators.
