摘要:
采用高温固相烧结法合成了一种高灵敏度的光致发光材料LiMgPO4:Tb,研究了其发光性能及辐射剂量学特性。本实验使用连续波光激励发光(CW-OSL)的模式对材料进行剂量学性能测测试,并探究了影响该材料OSL灵敏度的因素。实验结果表明,在掺杂剂浓度为0.2% mol、粒径为50-150μm时,该材料表现出较高的灵敏度。此外,还发现该材料有较好的剂量学特性,如较高的灵敏度(约为市售Al2O3:C的3倍),低有效原子序数(Zeff ≈ 11.8),及宽剂量响应范围(0.1~1kGy)等特性,使得该材料可潜在应用于个人及医疗辐射剂量在线检测等领域。
Abstract:
The goal of this work was to investigate the relevant dosimetric and luminescent properties of LiMg- PO4 :Tb a high sensitivity optically stimulated luminescence ( OSL) material, synthesized by a simple solid- state diffusion method. The dosimetric properties of the material using a continuous wave-optically stimulated luminescence ( CW-OSL) technique were studied. The influencing factors affecting the sensitivity of the OSL material were also explored. The experimental results showed that the material exhibited high sensitivity when the dopant concentration was 0. 2% mol and the particle size was 50 ~ 150 |xm. In addition, The material was found to have all the good dosimetric characteristics, such as high sensitivity ( 3 times less than the commercially available A12O3 :C, Landauer Inc., USA) , tissue equivalence (low-Z, Zeff« 11. 8) ,wide range of dose response ( 0. 1 Gy~ 1. 0 kGy) , etc., which made the material potential for personal and medical dosimetry applications in radiation dosimetry.
