- MULTI-DOPED LUTETIUM BASED OXYORTHOSILICATE SCINTILLATORS HAVING IMPROVED PHOTONIC PROPERTIES

摘要

The present invention is directed to a set of multi-doped cerium-activated scintillating materials of a rare earth silicate based solid solution having a composition comprising lutetium and represented by the formula: (Lu _{2-w-x + 2y} A _w Ce _x Si _1-y ) _1z Me _z J _j O _q and (Lu _2-wx-2y A _w Ce _x Si _{1+ y} ) _1-z Me _z J _j O _q . The present invention relates to high-energy physics, nuclear industry; Positron emission tomography (TOF PET and DOI PET scanner) and single photon emission computed tomography (SPECT), positron emission tomography (PET / MR) using magnetic resonance imaging; X-ray computer indirect shooting; It is useful for the detection of elementary particles and nuclei in non-destructive testing of solid state structures, including gamma-ray systems for inspection of airport security systems, trucks and cargo containers.
