Chloride scintillator for radiation detection

摘要

The present disclosure discloses, in one arrangement, a single crystalline chloride scintillator material having a composition of the formula A 3 MCl 6 , wherein A consists essentially of Li, Na K, Rb, Cs or any combination thereof, and M consists essentially of Ce, Sc, Y, La, Lu, Gd, Pr, Tb, Yb, Nd or any combination thereof. In another arrangement, a chloride scintillator material is single-crystalline and has a composition of the formula AM 2 Cl 7 , wherein A consists essentially of Li, Na K, Rb, Cs or any combination thereof, and M consists essentially of Ce, Sc, Y, La, Lu, Gd, Pr, Tb, Yb, Nd or any combination thereof. Specific examples of these scintillator materials include single-crystalline Cs 3 CeCl 6 , CsCe 2 Cl 7 , Ce-doped KGd 2 Cl 7 (KGd 2 ( 1- x )Ce 2 x Cl 7 ) and Ce-doped CsGd 2 Cl 7 (CsGd 2(1- x ) Ce 2 x Cl 7 ). In a further arrangement, the Bridgman method can be used to grown single crystals of the chloride scintillator materials compounds synthesized from starting chlorides.
