用自制的低温装置保持LiF晶体的温度为77K,同时用电子束辐照,产生了浓度高达1017cm-3的F2+心。并对F2+心荧光发射特性进行了实验观测和理论分析。LiF crystals were irradiated by electron beams at 77 K. F2+ centers were then produced in these crystals, the density of which reached as great as 1017 cm-3. The fluorescence emission characteristics of the F2+ centers were observed, and analysed theoretically.
