我们研究了掺Tb的LiCaAlF 6单晶的闪烁和剂量学特性。X射线诱导的发射光谱由几个尖锐的峰，由于4f-4f跃迁的Tb 3+离子。热释光（TL）光谱显示出类似的发射峰，在那些的X-射线诱导发光。的TL强度单调增加的X射线照射剂量的函数，和剂量响应被证明从0.01到10毫戈瑞。这些结果表明，Tb掺杂LiCaAlF 6单晶是一个很好的候选TL剂量计材料的低剂量应用。
We have investigated the scintillation and dosimetric properties of Tb-doped LiCaAlF6 single crystals. The X-ray-induced emission spectrum consisted of several sharp peaks due to the 4f–4f transitions of the Tb3+ ion. The thermoluminescence (TL) spectrum showed similar emission peaks as in those of the X-ray-induced luminescence. The TL intensity monotonically increased as a function of X-ray irradiation dose, and the dose response was demonstrated from 0.01 to 10 mGy. These results suggest that the Tb-doped LiCaAlF6 single crystal is a good candidate TL dosimeter material for low-dose applications.
