  • CERIUM DOPED RARE-EARTH ORTOSILICATE MATERIALS HAVING DEFECTS FOR IMPROVEMENT OF SCINTILLATION PARAMETERS
    Publication number: 20140291580
    Abstract: The present invention is a creation of advanced scintillation materials having emission maximum in the range of about 400-450 nm and based on cerium doped a rare-earth oxyorthosilicate including LFS, LSO, LYSO, LGSO, GSO crystals having defects in comparison with ideal crystal structure, and said defects change the optical transmission and absorption spectra in the range about of 200-340 nm. The picks of maximum absorptions characterised in that the ratio of A(?1=250-270 nm)/A(?3=280-300 nm)?1, A(?2=280-300)/A(?3=340-380)?1, A(?1=250-270)/A(?2=280-300 nm)>1.
