虽然镧系离子和有机配体的发光配合物已经得到了深入的研究，但相对而言，很少有人关注这些体系中镧系中心发光态的自然（或“辐射”）寿命。本文研究了著名的Judd-Ofelt理论对Eu3+配合物发射特性的适用性。此外，实验证明了Eu3+的D-5(0)激发态的辐射寿命可以不使用Judd-Ofelt理论直接从其校正的发射光谱中计算出来。我们还简要讨论了发现除Eu3+以外的镧系离子自然寿命的可能性。
Although luminescent complexes of lanthanide ions and organic ligands have been studied intensively, relatively little attention has been paid to the natural (or 'radiative') lifetime of the lanthanide centered luminescent state in these systems. Here, the applicability of the well-known Judd-Ofelt theory to the emissive properties of Eu3+ complexes is investigated. Moreover, it is demonstrated experimentally that the radiative lifetime of the D-5(0) excited state of Eu3+ can be calculated directly from its corrected emission spectrum, without using Judd-Ofelt theory. We also discuss briefly the possibility of finding the natural lifetimes of lanthanide ions other than Eu3+.
