【摘要】 以1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮 (PMBP)为第一配体,乙酰水杨酸(Aspirin)为第二配体,合成了一系列Eu／Tb不同比例(2:3,3:2,6:3) 的三元配合物。通过元素分析、红外光谱、摩尔电导率等测试,确定了配合物的组成与结构;通过紫外光谱、激发与发射光谱的测试,研究了配合物的荧光性质。配合物在固态状态下的发射光谱都表现出较强的三价铕离子的特征发射,铽能极大地增强铕的特征荧光,而铽的特征荧光确被铕猝灭了。更多还原

【Abstract】 In this paper, with l-phenyl-3-methyl-4-benzoyl-pyrazol-5-one(PMBP)as the first ligand and aspirin as the secondary ligand, ternary rare earth complexes with a sery of different ratios(2 : 3,3 :2,6:3) of Eu/Tb were synthesized. Their compositions and constructions were characrerized by elemental analysis, IR spectra and molar conductivity. Their fluorescent properties were studied by ultraviolet spectra and fluorescence spectra. Photo-luminescent studies showed that three complexes exhibited intense emission typical of europium ions Eu3+. The fluorescence emission intensity of europium ions were greatly sensitized by terbium ions and those of terbium ions were strongly quenched by europium ions.更多还原
