LiMgPO4∶Tb光致发光材料的制备及剂量学性能研究
Synthesis and OSL Studies of LiMgPO4∶Tb Material for Radiation Dosimetry
摘要
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 μm. In addition, The material was found to have all the good dosimetric characteristics, such as high sensitivity (3 times less than the commer-cially available Al2O3∶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 ap-plications in radiation dosimetry.关键词
