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.

Abstract: The invention relates to an inorganic rare-earth iodide scintillation material of formula A X Ln (y-y',) Ln' y' I (x+3y) in which: A represents at least one element selected among Li, Na, K, Rb, Cs; Ln represents at least one first rare-earth element selected among La, Gd, Y, Lu, said first rare-earth element having a valency of 3+ in the aforementioned formula: Ln' represents at least one second rare-earth element selected among Ce, Tb, Pr, said second rare-earth element having a valency of 3+ in the aforementioned formula, x is an integer and represents 0, 1, 2 or 3; y is an integer or non-integer greater than 0 and less than 3, and; y' is an integer or non-integer greater than 0 and less than y. This material presents a high stopping power, a rapid decay time, in particular, less than 100 ns, a good energy resolution (in particular, less than 6% at 662 keV) and a high luminous level. This material can be used in nuclear medicine equipment, in particular, in Anger-type gamma cameras and in positron emission tomography scanners.
