【摘要】 合成了具有摩擦发光及荧光性能的Ｅｕ３＋与苯甲酰三氟丙酮（ＨＴＡ、三苯基氧化磷（ＴＰＰＯ）的三元配合物．用同样方法合成的Ｓｍ３＋和Ｔｂ３＋的相同组成三元配合物仅有荧光特性．经元素分析及红外、紫外光谱测试，确定它们的化学式为Ｌｎ（ＴＰＰＯ）２（ＢＴＡ）２（ＮＯ３）（其中ｈ分别为Ｓｍ，Ｅｕ，Ｔｂ）．３种配合物在Ａｎｕｒｎ紫外灯光照射下能发出很强的特征荧光，Ｓｍ配合物为粉红色，Ｅｕ配合物为红色，Ｔｂ配合物为绿色．通过荧光光谱研究了它们的发光性质．Ｅｕ３＋三元配合物晶体只经玻璃棒轻轻摩擦便能发出闪烁明亮的红光（摩擦发光）．更多还原

【Abstract】 Three new rare earth(Eu, Sm, Tb) ternary complexes of benzoyltrifluoroacetoneand triphenylphosphine oxide are first prepaids. Their compositions are detennined having aformula of Ln(TPPO)2(BTA)2(NO3) by electal analysis. Their propeties are studied withUV, IR aborption and fiuorescence spodroscopy. Their possible structim are also proposed.更多还原
