Thermoluminescence properties of undoped and Dy doped MgBO compounds were studied with the irradiation of Cf source. The TL kinetic parameters of MgBO: Dy were studied by computer glow curve deconvolution (CGCD) method. The glow curve structures of 1% Dy doped magnesium tetraborate compound consists of at least five glow peaks with a main dosimetric peak at about 220 °C. The highest sensitivity which is approximately 1.90 and 1.47 times higher than that of TLD-600 and TLD-700 was found for MgBO: Dy (1 mol%). The results clearly showed that Dysprosium doped magnesium borate has a potential to be considered as the thermoluminescence neutron + gamma dosimeter.
在Cf源辐照下研究了未掺杂和Dy掺杂的MgBO化合物的热释光特性。采用计算机发光曲线解卷积(CGCD)方法研究了MgBO:Dy的热释光动力学参数。1% Dy掺杂的四硼酸镁化合物的发光曲线结构至少由五个发光峰组成,主剂量峰在约220 °C处。发现MgBO:Dy(1摩尔%)的最高灵敏度分别比TLD-600和TLD-700高约1.90倍和1.47倍。结果清楚地表明,Dy掺杂的硼酸镁有潜力被视为热释光中子+γ剂量计。
