Publication number: 20240174923Abstract: A scintillation compound can include a rare earth element that is in a divalent (RE2+) or a tetravalent state (RE4+). The scintillation compound can include another element to allow for better change balance. The other element may be a principal constituent of the scintillation compound or may be a dopant or a co-dopant. In an embodiment, a metal element in a trivalent state (M3+) may be replaced by RE4+ and a metal element in a divalent state (M2+). In another embodiment, M3+ may be replaced by RE2+ and M4+. In a further embodiment, M2+ may be replaced by a RE3+ and a metal element in a monovalent state (M1+). The metal element used for electronic charge balance may have a single valance state, rather than a plurality of valence states, to help reduce the likelihood that the valance state would change during formation of the scintillation compound.Type: ApplicationFiled: February 6, 2024Publication date: May 30, 2024Inventors: Samuel BLAHUTA, Eric E. MATTMANN, Damien PAUWELS, Bruno VIANA

Publication number: 20120119092Abstract: The invention relates to a scintillator material comprising a cerium-doped rare-earth silicate, characterized in that its absorbance at a wavelength of 357 nm is less than its absorbance at 280 nm. This material has an afterglow of generally less than 200 ppm after 100 ms relative to the intensity measured during an X-ray irradiation. It is preferably codoped. It may be obtained using an oxidizing anneal. It is particularly suited to integration in an ionizing particle detector that may be used in a medical imaging apparatus.Type: ApplicationFiled: December 23, 2010Publication date: May 17, 2012Applicant: SAINT-GOBAIN CRISTAUX ET DETECTEURSInventors: Samuel Blahuta, Eric Mattmann, Damien Pauwels, Bruno Viana

Patent number: 6818896Abstract: A monoclinic single crystal with a lutetium pyrosilicate structure is described. The crystal is formed by crystallization from a congruent molten composition of LU2(1-x)M2xSi2O7 where LU is lutetium or a lutetium-based alloy which also includes one or more of scandium, ytterbium, indium, lanthanum, and gadolinium; where M is cerium or cerium partially substituted with one or more of the elements of the lanthanide family excluding lutetium; and where x is defined by the limiting level of LU substitution with M in a monoclinic crystal of the lutetium pyrosilicate structure. The LU alloy should contain greater than about 75 weight percent lutetium. The crystals exhibit excellent and reproducible scintillation response to gamma radiation.Type: GrantFiled: July 18, 2002Date of Patent: November 16, 2004Assignee: Saint-Gobain Cristaux & DetecteursInventors: Damien Pauwels, Bruno Viana, Andree Kahn-Harari, Pieter Dorenbos, Carel Wilhelm Eduard Van Eijk
