  • 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.
