Li-codoped MgF₂:Tb ceramics with different Li concentrations (0.01, 0.1, 1, and 3 mol%) were prepared by the spark plasma sintering method, and photoluminescence (PL), scintillation, and dosimetric properties were investigated. Sharp peaks due to 4-4 f transitions of Tb³⁺ ion were observed in all of PL, scintillation, and thermally-stimulated luminescence (TSL). TSL glow curves confirmed that the TSL intensity was increased by Li-codoping without an increase of QY values. Especially, the TSL intensity was the highest in 1% Li-codoped MgF₂:Tb, which was approximately 2.2 times larger than that of MgF₂ doped with only Tb. Moreover, It was confirmed that the TSL responses of the 0.01, 0.1 and 1% Li-codoped MgF₂:Tb ceramics were very sensitive to irradiation dose and showed a good linearity from 0.01 to 1000 mGy.

通过火花等离子体烧结法制备了不同Li浓度（0.01、0.1、1和3 mol％）的Li掺杂MgF ₂：Tb陶瓷，并研究了光致发光（PL），闪烁和剂量特性。在所有的PL，闪烁和热激发发光（TSL）中均观察到由于Tb ³⁺离子的4-4 f跃迁而导致的尖峰。TSL辉光曲线证实，通过锂共掺杂可提高TSL强度，而不会增加QY值。尤其是，在1％的Li掺杂的MgF ₂：Tb中，TSL强度最高，约为仅掺杂Tb的MgF _2的2.2倍。此外，已证实0.01、0.1和1％的Li掺杂MgF的TSL响应₂：Tb陶瓷对辐照剂量非常敏感，并且在0.01至1000 mGy之间显示出良好的线性。
