A new α-AlO doped with Tm ions was obtained by combustion method; doped α-AlO in the powder form was mixed with polytetrafluoroethylene resin (PTFE) to obtain dosimeters in pellet form, in order to be used as radiation dosimeter. The glow curve, linearity, lower detection limit, repeatability and fading, were studied. The kinetic parameters were determined by deconvolution method. Morphological characteristics were studied by low vacuum scanning electron microscopy and X-ray diffraction. Results showed that α-AlO+PTFE obtained is a promising material to radiation dosimetry.
通过燃烧法制备了一种掺有铥离子的新型α-AlO；将粉末形式的掺杂α-AlO与聚四氟乙烯树脂（PTFE）混合，以获得丸粒形式的剂量计，用作辐射剂量计。研究了其发光曲线、线性、下限检测限、重复性和褪色情况。通过去卷积法确定了动力学参数。通过低真空扫描电子显微镜和X射线衍射研究了形态特征。结果表明，所获得的α-AlO+PTFE是一种有前途的辐射剂量学材料。
