  • Patent number: 9441154
    Abstract: In one embodiment, a crystal includes at least one metal halide; and an activator dopant comprising ytterbium. In another general embodiment, a scintillator optic includes: at least one metal halide doped with a plurality of activators, the plurality of activators comprising: a first activator comprising europium, and a second activator comprising ytterbium. In yet another general embodiment, a method for manufacturing a crystal suitable for use in a scintillator includes mixing one or more salts with a source of at least one dopant activator comprising ytterbium; heating the mixture above a melting point of the salt(s); and cooling the heated mixture to a temperature below the melting point of the salts. Additional materials, systems, and methods are presented.

  • Publication number: 20050241570
    Abstract: The invention relates to a crucible (I) adapted for growing a large crystal, starting with an adequate raw material, comprising a receptacle (1) intended to accommodate the large crystal, wherein moreover, directly beneath the receptacle (1) a vertical succession of at least two containers (31, 32, 33, 3n) is located, with each container being connected by a restriction zone (41, 42, 43, 4n) to the successive container located directly above, and with the upper container (33, 3n) being connected by a restriction zone (43, 4n) to the receptacle (1), as well as a growth method that implements said crucible.
