Abstract
Mixed halide scintillation materials of a first general formula A4B(1-y)MyX′6(1-z)X″6z and a second general formula A(4-y)BMyX′6(1-z)X″6z are disclosed. In the general formulas, A is an alkali metal, B is an alkaline earth metal, and X′ and X″ are two different halogen atoms. Scintillation materials of the first general formula include a divalent external activator M such as Eu2+ or Yb2+ or a trivalent external activator M such as Ce3+. Scintillation materials of the second general formula include a monovalent external activator M such as In+, Na+, or Tl+ or a trivalent external activator such as Ce3+.
