中文摘要	采用高温熔融法,在还原气氛(CO)下制备了Ce~(3+)掺杂的Gd_2O_3基氟氧闪烁玻璃,系统地研究了BaF_2对闪烁玻璃密度,光学性能以及闪烁性能的影响。比较了闪烁玻璃与BGO晶体在紫外激发以及X射线激发下的荧光强度。结果表明:BaF_2增加玻璃的密度,且BaF_2含量越高,玻璃密度越大;BaF_2能增强Ce~(3+)的紫外以及X射线激发发光,BaF_2的最佳摩尔分数为15%;BaF_2含量相同时,由于电荷迁移猝灭以及Gd~(3+)的浓度猝灭,随着Gd_2O_3含量增加,Ce~(3+)的紫外激发以及X射线激发发光强度逐渐降低,X射线激发的光谱积分强度从相当于BGO的143%下降到BGO的19%,荧光寿命从46.5 ns降低到30.5 ns。该玻璃的光致发光强度明显强于BGO晶体,但是闪烁发光却弱于BGO晶体。
英文摘要	Ce~(3+)- doped Gd_2O_3 based oxyfluoride scintillation glasses are prepared through high-temperature melt-quenching method under CO atmosphere. The effect of BaF_2 on the density, optical properties and scintillation properties are studied. Luminescence intensity of scintillation glasses and BGO crystal excited by ultraviolet (UV) and X- ray are compared. The result shows that the density can be increased by BaF_2. The more the BaF_2 concentration is, the higher the density is. BaF_2 can enhance the UV-excited luminescence and X-ray excited luminescence. The optimum mole fraction of BaF2is 15%. Due to charge transferring quenching and concentration quenching of Gd~(3+), the UV-excited luminescence and X-ray excited luminescence decrease with the increase of Gd_2O_3 concentration. The integrated light emission intensity of these glass samples excited by X-ray decreases from 143% of BGO to 19% of BGO and decay time reduces from 46.5 ns to 30.5 ns. The photoluminescence of the glasses is higher than that of BGO, while the radioluminescence is lower than that of BGO.
