摘　　要：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RisF TL/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431 K和482 K两个热释光峰,482 K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 431 K and 482 K, 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 firstorder peak. The TL response of YAP：Cu crystal shows excellent linear characteristics in the dose range of 10-5- 102 Gy. YAP：Cu cryshul is a potential iotxization irradiation dosimetry material with excellent TL properties.
