报道了掺铈硅酸镥Lu_2SiO_5：Ce ~（3+）闪烁晶体的绝对光产额。从60 keV到1 MeV以上，光输出随γ射线能量线性增加，约为NaI（Tl+）的67%。然而，对于5至60 KeV之间的X射线能量，观察到非线性响应。为了比较，我们还研究了Gd_2SiO_5：Ce ~（3+）晶体和CsI：Tl晶体的光产额随激发能的变化。
The absolute light yield of cerium doped lutetium oxyorthosilicate Lu2SiO5:Ce3+ (LSO:Ce) scintillation crystals is presented. From 60 keV to above 1 MeV the light output increases linearly with the gamma-ray energy and is about 67% of that of NaI(Tl+). However, a non-linear response is observed for X-ray energies between 5 and 60 KeV. For comparison, we also studied the light yield of a Gd2SiO5:Ce3+ crystal and a CsI:Tl crystal as a function of excitation energy.
