摘要

用水热法制备钆掺杂的氟化钙（CaF,2,：Gd）纳米材料。采用X射线衍射、扫描电子显微镜、能谱仪等方法对其进行表征，发现CaF,2,：Gd材料样品平均粒径44 nm，晶体呈立方晶系结构，样品组成元素为Ca、F、Gd。运用,T,m,-,T,stop,与CGCD（Computerized Glow Curves De-convolved）相结合的方法对发光曲线进行解谱，确定材料发光曲线的4个重叠峰分别为126、148、174、286℃，并得到了各发光峰的动力学参数。结果表明，制备的CaF,2,：Gd纳米材料对于γ射线在1~10 000 Gy内都有良好的线性剂量响应，兼顾良好的重复性和衰减性，稀土元素Gd的最优掺杂物质的量浓度为0.6%。制备的CaF,2,：Gd纳米材料可以用作高剂量γ射线测量。

Abstract

Gadolinium doped calcium fluoride (CaF,2,:Gd) nanoparticles were prepared by the hytrothermal method. X-ray diffraction (XRD), Scanning electron microscope (SEM), and Energy dispersive spectrometer (EDS) were used to characterize the nanomaterials and obtained the 44 nm average particle size, the cubic crystal and element compose (Ca, F, Gd). The combination of ,T,m,-,T,stop, and CGCD (Computerized glow curves de-convolved) were used and four overlapping peaks were found in glow curve at 126, 148, 174 and 286℃. And the kinetic parameters of the synthesized nanomaterials were also obtained. The optimal Gd mole percent was found at 0.6%. A good linear dose response was shown from 1 Gy to 10 000 Gy. The fading and repeatability of the nanoparticles were also excellent. It can be concluded that the CaF,2,:Gd nanomaterials could be employed to measure the high dose gamma radiation.
