A scintillator composition includes a matrix material, where the matrix material includes an alkaline earth metal and a lanthanide halide. The scintillator composition further includes an activator ion, where the activator ion is a trivalent ion. In one embodiment, the scintillator composition includes a matrix material represented by A 2 LnX 7 , where A includes an alkaline earth metal, Ln includes a lanthanide ion, and X includes a halide ion. In another embodiment, the scintillator composition includes a matrix material represented by ALnX 5 , where A includes an alkaline earth metal, Ln includes a lanthanide ion, and X includes a halide ion. In these embodiments, the scintillator composition includes an activator ion, where the activator ion includes cerium, or bismuth, or praseodymium, or combinations thereof. |
