Abstract:
A scintillator composition is described. The scintillator composition includes a matrix material and an activator. The matrix material includes at least one alkali metal or thallium; at least one alkali metal, different than the previously selected alkali metal; at least one lanthanides; and at least two halogens. The activator is cerium. Further, radiation detectors, which include the scintillator composition and methods for detecting high-energy radiation are also described and form part of this disclosure.
