A series of magnesium sulphate phosphors MgSO4:RE3+,X ( RE = Dy, Tm, Eu and X = P, Mn) have been prepared and studied. Based on the experimental results of thermoluminescence (TL) emission spectra and dose responses studies, it is proposed that in these phosphors large defect complexes are formed, which include intrinsic imperfections and dopants. These defect complexes were formed in the course of preparation of phosphors and could be regarded as basic elements in the TL multi-stage processes. This defect model might be applicable to the most of TL materials.
已经制备并研究了一系列硫酸镁磷光体MgSO₄:RE³⁺,X（RE = Dy、Tm、Eu且X = P、Mn）。基于热释光（TL）发射光谱和剂量响应研究的实验结果，有人提出在这些磷光体中形成了大的缺陷复合体，其中包括本征缺陷和掺杂剂。这些缺陷复合体是在磷光体制备过程中形成的，可被视为TL多阶段过程中的基本元素。这种缺陷模型可能适用于大多数TL材料。
