| 摘 要： | 探讨Ｂａ２＋离子搀杂对（Ｃａ０．５Ｓｒ０．５）５（ＰＯ４）３Ｃｌ：Ｅｕ２＋和（Ｃａ０．４Ｓｒ０．６）５（ＰＯ４）３Ｃｌ：Ｅｕ２＋量子发光效率的影响。当用Ｂａ２＋离子代替Ｃａ２＋或Ｓｒ２＋离子进入晶体时，Ｅｕ２＋离子的发光特性发生改变：发射峰的峰值降低，热猝灭的温度升高。并采用位型坐标理论给予解释。根据晶体的结构特征，对占据两个不等当晶体学位置的Ｅｕ２＋离子发光中心之间的能量传递进行了探讨

| Abstract: | The influence of Ba 2+ impurities on the luminescence quantum efficiency of (Ca 0.5 Sr 0.5 ) 5(PO 4) 3Cl: Eu 2+ and (Ca 0.4 Sr 0.6 ) 5(PO 4) 3Cl: Eu 2+ have been studied. With the Ba 2+ substitution for the Ca 2+ or Sr 2+ into the crystall, the luminescence properties of Eu 2+ has changed: the emission peak lowered and the thermal quenching temperature increased. Energy transfer between two unequivalent Eu 2+ centers has been evaluated quantitatively. |
