摘要: 本文研究了氮氧稳定自由基对九种L_4EuQH型配合物荧光的猝灭行为, 结果表明猝灭速率远小于扩散速率, 并根据实验结果提出猝灭作用球内猝灭几率不为1的观点。

Abstract: The fluorescence quenching of nine L_4EuQH type complexes by stable free radical was studied. Results show that the bimolecular quenching constants were much less than the diffusion rate constant and the existence of a sphere of action within which the probability of quenching is not unity as usually reported in current literature.
