| 摘 要： | 应用时间分辨荧光光谱方法研究了微环境对Eu~(3+)络合物发光的影响,测定了NCS~-对Eu(TTA)_3和Eu(DB)_3的荧光猝灭。实验表明,Eu~(3+)的~5D_0能级弛豫速率K_0随NCS~-的引入而增大,NCS~-离子导致的微环境变化,影响了Eu~(3+)的Laporte选择规则,改变了Eu~(3+)与配位体间相互作用的程度。

| Abstract: | The luminescence of Eu~(3+) complexes influenced by microenvironments and the fluorescence quenching of Eu(TTA)_3 and Eu(DB)_3 with NCS~- added have been studied with timeresolved fluorescence spectrometry. The experiments show that the relaxation rate k_0 of the ~5D_0 level in Eu~(3+) increases with the introduce of NCS~- anions. In the result, the microenvironment change caused by the introduce of NCS~- anions influences on Laporte selective law of Eu~(3+) ions and intereaction between Eu~(3+) and the ligands. |
