  • Scintillator compositions of cerium halides, and related articles and processes
    Publication number: 20060197023
    Abstract: A scintillator composition is disclosed, containing a solid solution of at least two cerium halides. A radiation detector for detecting high-energy radiation is also described herein. The detector includes the scintillator composition mentioned above, along with a photodetector optically coupled to the scintillator. A method for detecting high-energy radiation with a scintillation detector is also described, wherein the scintillation crystal is based on a mixture of cerium halides.

  • Scintillator compositions, and related processes and articles of manufacture
    Patent number: 7084403
    Abstract: Scintillator materials based on certain types of halide-lanthanide matrix materials are described. In one embodiment, the matrix material contains a mixture of lanthanide halides, i.e., a solid solution of at least two of the halides, such as lanthanum chloride and lanthanum bromide. In another embodiment, the matrix material is based on lanthanum iodide alone, which must be substantially free of lanthanum oxyiodide. The scintillator materials, which can be in monocrystalline or polycrystalline form, also include an activator for the matrix material, e.g., cerium. Radiation detectors that use the scintillators are also described, as are related methods for detecting high-energy radiation.
