Scintillator crystals, method for making same, user thereof

A monoclinic single crystal with a lutetium pyrosilicate structure is described. The crystal is formed by crystallization from a congruent molten composition of LU M Si O where LU is lutetium or a lutetium-based alloy which also includes one or more of scandium, ytterbium, indium, lanthanum, and gadolinium; where M is cerium or cerium partially substituted with one or more of the elements of the lanthanide family excluding lutetium; and where x is defined by the limiting level of LU substitution with M in a monoclinic crystal of the lutetium pyrosilicate structure. The LU alloy should contain greater than about 75 weight percent lutetium. The crystals exhibit excellent and reproducible scintillation response to gamma radiation.
