  • Scintillator crystals, method for making same, use thereof
    Patent number: 7479637
    Abstract: The invention concerns an inorganic scintillator material of general composition M1?xCexCl3, wherein: M is selected among lanthanides or lanthanide mixtures, preferably among the elements or mixtures of elements of the group consisting of Y, La, Gd, Lu, in particular among the elements or mixtures of elements of the group consisting of La, Gd and Lu; and x is the molar rate of substitution of M with cerium, x being not less than 1 mol % and strictly less than 100 mol %. The invention also concerns a method for growing said monocrystalline scintillator material, and the use of said scintillator material as component of a scintillating detector in particular for industrial and medical purposes and in the oil industry.
    Type: Grant

    Date of Patent: January 20, 2009
    Assignee: Stichting Voor de Technische Wetenschappen
    Inventors: Pieter Dorenbos, Carel Wilhelm Eduard Van Eijk, Hans-Ulrich Gudel, Karl Wilhelm Kramer, Edgar Valentijn Dieuwer Van Loef
  • Scintillator crystals, method for making same, use thereof
    Patent number: 7250609
    Abstract: The invention concerns an inorganic scintillator material of general composition M1-xCexBr3, wherein: M is selected among lanthanides or lanthanide mixtures of the group consisting of La, Gd, Y in particular among lanthanides or lanthanide mixtures of the group consisting of La, Gd; and x is the molar rate of substitution of M with cerium, x being not less that 0.01 mol % and strictly less than 100 mol %. The invention also concerns a method of growing such a monocrystalline scintillator material, and the use of same as component of a scintillating detector for industrial and medical purpose or in the oil industry.
