| 摘要: 在77K下测定了Eu(TTA)3·1/2(4,4′-bipyN2O2)配合物的激发光谱、发光光谱和时间分辨光谱。光谱数据表明,在标题配合物中存在化学环境不同的两种Eu3+格位,但它们的局部对称性都属于C2V点群,这可能表明该配合物的激发态电子结构稍有不同. |

| Abstract: his paper reports the high resolution laser excited excitation, luminescence and time resolved luminescence spectra of complex Eu(TTA)3·1/2(4,4′-bipyN2O2) at 77K. Spectrum data show that the complex possesses two Eu3+ sites with an energy difference of 9 cm-1 of 5D0 levels in excited state. Their local symmetries of both sites, however, are C2v. This may be understood that a slight difference in electronic structure exists between the two sites of excited state. |
