The aim of this work was to study the optically stimulated luminescence (OSL) properties of novel MgO co-doped with different lanthanides and lithium ions as well as to evaluate the feasibility of using the mentioned phosphors as OSL dosimeters. In this context, the OSL efficiency corresponding to different stimulation wavelengths and different filters was analyzed for all the samples. The properties of the most efficient material, namely, MgO-La(OH), were further studied. Moreover, the repeatability and linearity of the OSL response, the fading of the OSL signal and the minimum detectable dose were investigated. Finally, feasibility of using these compounds in OSL dosimetry was assessed.
这项工作的目的是研究掺有不同镧系元素和锂离子的新型氧化镁的光激发发光（OSL）特性，并评估使用上述磷光体作为OSL剂量计的可行性。在此背景下，分析了所有样品对应于不同激发波长和不同滤光片的OSL效率。对最有效的材料即MgO-La(OH)的特性进行了进一步研究。此外，还研究了OSL响应的重复性和线性、OSL信号的衰减以及最小可探测剂量。最后，评估了在OSL剂量测定中使用这些化合物的可行性。
