Abstract

The non-doped and Tb: Li₆Gd(BO₃)₃ single crystals with varying Tb concentrations (0.1–10 mol%) were synthesized using the floating zone method. The synthesized Li₆Gd(BO₃)₃ single crystals were analyzed for their photoluminescence (PL) and thermally stimulated luminescence (TSL) properties. In both PL and TSL spectra, the non-doped and Tb: Li₆Gd(BO₃)₃ single crystals exhibited emission peaks corresponding to the transitions from the ground state to the excited states of Gd³⁺ and Tb³⁺ ions, respectively. The detection limit of the 1 mol% Tb: Li₆Gd(BO₃)₃ single crystal was 0.1 mGy, as determined from the TSL dose response function. The 1 mol% Tb: Li₆Gd(BO₃)₃ single crystal exhibited a spatial resolution of 10.0 LP/mm after 3 Gy X-ray irradiation.

Tb浓度对Li6Gd(BO3)3单晶光致发光和热激发发光的影响

采用浮区法合成了不同Tb浓度（0.1 ~ 10 mol%）的未掺杂和Tb: Li6Gd(BO3)3单晶。对合成的Li6Gd(BO3)3单晶的光致发光（PL）和热激发发光（TSL）性能进行了分析。在PL和TSL光谱中，未掺杂和Tb: Li6Gd(BO3)3单晶的发射峰分别对应于Gd3+和Tb3+离子从基态到激发态的跃迁。通过TSL剂量响应函数确定了1 mol% Tb: Li6Gd(BO3)3单晶的检出限为0.1 mGy。1mol % Tb: Li6Gd(BO3)3单晶经3gy x射线辐照后的空间分辨率为10.0 LP/mm。
