| 摘 要： | 在77K测定了标题配合物的激发光谱和荧光光谱,在配合物的7F0→5D0激发光谱里,580.14nm和580.68nm处呈现两个锐锋,说明在该配合物中存在两种Eu3+格位.选择激发配合物的5D0能级,得到两组完全不同的5D0→7FJ(J=1,2)荧光光谱,表明配合物中Eu3+离子具有不同的化学环境,两种格位的可能点群是C1,C2或Cs,可能具有与Y2(p-CH3C6H4COO)6(C12H8N2)2类似的晶体结构.

| Abstract: | Coordination compound of Eu(DMBA)\-3Phen has been synthesized.In Eu(DMBA)\-3Phen Eu stands for europium,DMBA represents 3,4-dimethyl benzoate,Phen is abbreviated from phenanthroline.At 77K excitation spectra,high resolution fluorescence spectra is recorded.Spectral data show that there are two Eu 3+ sites with different chemical envibronment in the Eu(DMBA)\-3Phen complex.The local symmetries for the central metal ions are C 1,C 2 of C s . |
