Title: Divalent-ion-doped single crystal alkali halide scintillators

Abstract

A single crystal composition includes an alkali halide crystal doped with a divalent element in the amount of 0.5 to 5 weight percent, the doped crystal having an optical transmission of at least 45% at at least one wavelength. An alkali halide doped with at least one of europium and ytterbium is particularly useful as a scintillator.
