MULTI-DOPED LUTETIUM BASED OXYORTHOSILICATE SCINTILLATORS HAVING IMPROVED PHOTONIC PROPERTIES

摘要

The present invention relates to a set of multi-doped cerium-activated scintillation materials of the solid solutions on the basis of the rare earth silicate, comprising lutetium and having compositions represented by the chemical formulas: (Lu2-w-x+2yAwCexSi1-y)1-zMexJjOq and (Lu2-w-x-2yAwCexSi1+y)1-zMezJjOq. The invention is useful for detection of elementary particles and nuclei in high-energy physics, nuclear industry; medicine, Positron Emission Tomography (TOF PET and DOI PET scanners) and Single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography with Magnetic Resonance imaging (PET/MR); X-ray computer fluorography; non-destructive testing of solid state structure, including airport security systems, the Gamma-ray systems for the inspection of trucks and cargo containers.
