Patent ID: 8486300

Claim:
An inorganic scintillator having the formula: Sr 1-y′-y Ba y′ X 1 x X 2 2-x :Ln y (I); wherein X 1 is a first halogen element, X 2 is a second halogen element, X 1 and X 2 are not the same halogen element and are each independently Cl, Br, or I, Ln is a lanthanide with a valence of 2+, x has a value having the range 0<x≦2, y′ has a value having the range 0≦y′<1, y has a value having the range 0<y≦1, and y′+y<1; and the inorganic scintillator is a single crystal having at least one dimension of a length of at least 1 mm, or a length at least sufficient to stop or absorb gamma-radiation.
