采用中频感应提拉法生长了高光学质量的YAP:Cu(原子数分数为0.5%)单晶，使用RisFTL/OSL-DA-15型热释光(TL)和光释光(OSL)仪系统研究了其TL 性能。研究结果表明：YAP:Cu单晶存在431K和482K两个热释光峰，482K处为主发光峰；TL峰位置不随辐照剂量的变化而变化,显示其为一级动力学峰；YAP:Cu单晶的TL 辐射剂量响应在10-5-102Gy范围内呈较好的线性关系。YAP:Cu晶体是一种TL性能优良并具有潜在应用价值的电离辐射剂量计材料。

The thermoluminescence (TL) properties of high quality 0.5% atom fraction Cu doped YAP crystal (YAP:Cu) which is grown by medium-frequency induction Czochralski method is systematically studied by RisF TL/OSL–DA-15. The research results show that, YAP:Cu crystal has two TL peaks which locates at 431K and 482K, and the 482 K peak is the main glow peak. The peak position does not shift with the change of irradiation dose and belongs to the first- order peak. The TL response of YAP:Cu crystal shows excellent linear characteristics in the dose range of 10- 5- 102 Gy. YAP:Cu crystal is a potential ionization irradiation dosimetry material with excellent TL properties.
