Nanodiamond thin films were deposited onto Si (100) substrates using Tequila as precursor by pulsed-liquid injection chemical vapour deposition at 850 degrees C. Some samples were exposed to beta particle irradiation in the dose range from 100 to 1600 Gy, and it was found that the thermoluminescence (TL) response is a linear function of dose. The glow curve displays two maxima centred at 170 and 350 degrees C, which does not shift when dose changes, indicating that first-order kinetics processes are involved. From the results, it is concluded that the new nanodiamond films are promising high-dose TL dosimeters.
通过脉冲液体注入化学气相沉积法，以龙舌兰作为前驱体，在850摄氏度的条件下，将纳米金刚石薄膜沉积在硅（100）衬底上。一些样品受到了剂量范围为100至1600戈瑞的β粒子辐照，结果发现热释光（TL）响应是剂量的线性函数。发光曲线显示出两个最大值，分别位于170摄氏度和350摄氏度，当剂量变化时，其位置并不移动，这表明涉及一级动力学过程。从结果可以得出结论，新型纳米金刚石薄膜有望成为高剂量热释光剂量计。
