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 Y/sub y/-doped Gd/sub 2-x/SiO/sub 5/: Ce/sub x/ (Y: Mg, Zr, Ta, x=0.5%, y=0.0002%/spl sim/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.

Mg、Zr、Ta掺杂对Gd/sub 2/SiO/sub 5/:Ce晶体闪烁性能的影响

我们通过掺杂Mg, Zr, Ta来开发新的GSO:Ce闪烁体材料，以改善医学成像扫描仪(如正电子发射断层扫描仪(PET))的闪烁性能。生长出Y/sub - Y掺杂Gd/sub - 2-x/SiO/sub - 5/: Ce/sub -x/晶体(Y: Mg, Zr, Ta, x=0.5%， Y =0.0002%/spl sim/0.03%)。测量了晶体的闪烁衰减曲线、上升时间、光输出和光透过率。发现GSO:Ce,Zr的光学透明度有所改善。
