Abstract

Undoped and Ti-doped CaSiO₃ single crystals were synthesized by the floating zone method, and the photoluminescence (PL) and thermoluminescence (TL) properties were researched. From the measurements of the PL and TL spectra, the emission origin of all the samples would be due to charge transfer between Ti⁴⁺ and O²⁻. In addition, all the samples indicated TL glow peaks at 70, 130, 270, and 360 °C. As a result, the 0.3 % Ti-doped sample showed a dynamic range between 0.1 and 1000 mGy, reusability, and fading of 10–30 % for a week.

ti掺杂CaSiO3单晶的热释光性质

采用浮区法合成了未掺杂和掺钛的CaSiO3单晶，并对其光致发光（PL）和热致发光（TL）性能进行了研究。从PL和TL光谱的测量来看，所有样品的发射源都是由于Ti4+和O2−之间的电荷转移。此外，所有样品在70、130、270和360°C处都有TL发光峰。结果表明，掺钛量为0.3%的样品动态范围在0.1 ~ 1000 mGy之间，可重复使用，衰减幅度为10 - 30%，持续时间为一周。
