20140185639 | GROUP III-V SUBSTRATE MATERIAL WITH THIN BUFFER LAYER AND METHODS OF MAKING - A substrate comprises a Group III-V material having an upper surface and a buffer layer having a thickness of not greater than about 1.3 μm and overlying the upper surface of the substrate. A plurality of optoelectronic devices formed on the substrate having a normalized light emission wavelength standard deviation of not greater than about 0.0641 nm/cm | 07-03-2014 |
20140097385 | DENSE HIGH-SPEED SCINTILLATOR MATERIAL OF LOW AFTERGLOW - The invention relates to an inorganic scintillator material of formula Lu | 04-10-2014 |
20130020488 | Detector with a Conical Scintillator - A detector of ionizing radiation comprises a photodetector and a scintillator in the shape of truncated cone comprising a large base, a small base and a lateral surface, the large base of the scintillator being coupled to the photodetector, any half-angle at the apex of the cone being in the range between 5° and 35°, the lateral face being coated with a black coating. The detector in accordance with an embodiment can produce a very short pulse. | 01-24-2013 |
20120286165 | Rare-Earth Halide Crystal Scintillator With Polished Sensitive Face - The invention relates to a single-crystal scintillator material comprising at least 50 wt % of rare-earth halide and comprising a polished first face. This material is integrated into an ionizing-radiation detector comprising a photoreceiver, the photoreceiver being optically coupled to the material via a face other than the polished first face. The material provides a good energy resolution and a high light intensity. The polishing may be carried out whatever the crystal orientation of the crystal. Loss of material due to this orientation is therefore prevented. | 11-15-2012 |
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 |
