摘要: 本文简要地介绍闪烁光纤的工作原理,指出了掺Tb~(3+)和Ce~(3+)闪烁玻璃光纤的谱特性和衰变时间常数,将它们和CeF_3与其它元机闪烁材料的特性进行了比较,从而得知CeF_3及掺Ce~(3+)闪烁玻璃光纤存在着潜在的巨大应用市场。 The working principle of scintillating fibers is briefly introduced in this paper. Thedecay time constant and spectral properties of the scintillating fibers of Tb_2O_3 and Ce_2O_3 glass aregiven. Comparing the properties of materials above and CeF_3 with those of other inorganic scintillatingmaterials, we find that CeF_3 and scintillating fibers of the Ce_2O_3 have an immense potential applicationmarket.
