  • Abstract
    We developed new GSO:Ce scintillator materials by doping Mg, Zr, Ta to improve scintillation properties for medical imaging scanners such as a positron emission tomograph (PET). The crystals of Yy-doped Gd2-xSiO5: Cex (Y: Mg, Zr, Ta, x=0.5%, y=0.0002%∼0.03%) were grown. The scintillation decay curve, rise time, light output and optical transmittance of these crystals were measured. Improvement of optical transparency was found for GSO:Ce,Zr.
