摘要
采用常温搅拌法制备了配合物Eu(BTF)3phen(BTF=苯甲酰三氟丙酮,phen=邻菲罗啉),改善稀土铕配合物的荧光性能。对配合物的热稳定性和荧光性质进行了测定,结果表明其具有良好的热稳定性,在362 nm激发光激发下,能发射强烈的、来自于Eu3+离子的特征红光,最大发射峰在612 nm,半峰宽大约为8 nm。对邻菲罗啉中性配体进行了两种不同的分子修饰,荧光光谱测试表明,邻菲罗啉配体上引入不同数目的基基团,在一定程度上改善了Eu(BTF)3phen配合物的荧光性能。
In order to improve the fluorescence properties of europium complex, Eu（BTF）3 phen （BTF=Benzoyltrifluoroacetone, phen=o-phenanthroline） was synthesized by the method of stirring method at room temperature. The results showed that the complex has good thermal stability. The complex emitted a strong characteristic red light which was from Eu3＋ under the exciting light of 362 nm. The maximum emission peak was at 612 nm. The full width at half maximum （FWHM） was 8 nm. Two different molecular modifications of the phenanthroline neutral ligands were carried out. The fluorescence spectra analysis showed that the fluorescent properties of Eu（BTF）3phen was improved by the groups onto the phenanthroline ligands. introduction of different numbers of neighborhood
