通过对光激励发光读出过程中各种电子转移过程的分析,建立了描述该过程的动力学方程组,通过求解在理论上得出了X射线影像存储材料中读写信号之间的线性关系。制备了X射线影像存储材料DaFCl:Eu~(2+),通过光谱测试在实验上验证了这一关系。 Through the analysis of various electron transfer processes during the photoexcitation luminescence readout, a kinetic equation set describing the process is established. The linear relationship between the read and write signals in the X-ray image storage material is theoretically obtained . The X-ray image storage material DaFCl: Eu ~ (2+) was prepared, and the relationship was verified experimentally by spectroscopy.
