| 20120119092 | SCINTILLATING MATERIAL HAVING LOW AFTERGLOW - 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. | 05-17-2012 |
| 20110297882 | DENSE HIGH-SPEED SCINTILLATOR MATERIAL OF LOW AFTERGLOW - The invention relates to an inorganic scintillator material of formula Lu | 12-08-2011 |
| 20110294298 | TEXTURED SINGLE CRYSTAL - A method for fabricating a textured single crystal including depositing pads made of metal on a surface of a single crystal. A protective layer is deposited on the pads and on the single crystal between the pads; and etching the surface with a first compound that etches the metal more rapidly than the protective layer is carried out. Processing continues with etching the surface with a second compound that etches the single crystal more rapidly than the protective layer; and etching the surface with a third compound that etches the protective layer more rapidly than the single crystal. The textured substrate may be used for the epitaxial growth of GaN, AlN or III-N compounds (i.e. a nitride of a metal the positive ion of which carries a +3 positive charge) in the context of the fabrication of LEDs, electronic components or solar cells. | 12-01-2011 |
| 20110293499 | METHOD FOR PREPARING RARE-EARTH HALIDE BLOCKS - The invention relates to a method of preparing a polycrystalline block of a halide of formula A | 12-01-2011 |
| 20110017914 | Ionizing Radiation Detector - The invention concerns an ionizing radiation detector comprising a housing containing:
| 01-27-2011 |
| 20110017911 | RARE-EARTH HALIDE SCINTILLATOR COATED WITH A LIGHT ABSORBER OR LIGHT REFLECTOR - A scintillator material comprises a rare-earth halide coated with a layer comprising a resin and a pigment. In an embodiment, the scintillator material is used in an ionizing-radiation detector, and in particular embodiment, a gamma camera. The layer can adhere well and act as an absorbent or reflector depending on the color of the pigment. | 01-27-2011 |

| 20100065778 | DENSE HIGH-SPEED SCINTILLATOR MATERIAL OF LOW AFTERGLOW - The invention relates to an inorganic scintillator material of formula Lu | 03-18-2010 |
| 20090246495 | ANNEALING OF SINGLE CRYSTALS - The invention relates to a process for manufacturing a single crystal comprising a rare-earth halide, having improved machining or cleavage behaviour, comprising heat treatment in a furnace, the atmosphere of which is brought, for at least 1 hour, to between 0.70 times T | 10-01-2009 |
| 20090140153 | Ionizing Radiation Detector - The invention concerns an ionizing radiation detector comprising a housing containing:
| 06-04-2009 |
