| 摘 要： | 通过改变紫外线的辐射照能量范围，研究了Ｅｕ＾２＋：ＢａＦＣｌ的光激励发光性质。发现紫外线能量大于Ｅｕ＾２＋的最低激发态能量及紫外线的能量小于Ｅｕ＾２＋最低激发态的能量两种情况下，光激励发光具有明显的差异，分析了产生差异的原因，给出了紫外线的辐照能量发生转时所对应的能级位置。

| Abstract: | The photostimulable luminescence (PSL) of Eu2+: BaFCl phosphors is studied through changing the energy of UV-irradiation. There are obviously difference of PSL both the energy of irradiation is larger than that of the minimum excitation and the energy of ultraviolet irradiation is smaller than that of minimum excitation. The reasons for the above difference are discussed and the location of the transform energy levels of ultraviolet irradiation from excitation to bleaching is given. |
