摘　　要：稀土配合物独特的发光性质使其在众多领域有很大的应用价值。其中, d-f跃迁发光稀土配合物具有跃迁宇称允许、激发态寿命短和光谱可调等特点,但相关研究还有待进一步深入。本文介绍了稀土配合物的发光机制,综述了具有d-f跃迁发光性质的稀土配合物(主要是Ce^(3+), Eu^(2+), Yb^(2+)和Sm^(2+)配合物)的研究进展,并初步总结了配合物分子结构对d-f跃迁发光性质的影响规律。The unique luminescence properties of rare earth complexes endow them with great value of application in many fields. Among them, luminescent rare earth complexes based on d-f transition have the characteristics such as allowed transition parity, short excited state lifetime, and adjustable spectrum. However, the related study is insufficient and further research is needed. This article introduced the luminescence mechanism of rare earth complexes and gave an overall review on the research progress of d-f transition based luminescent rare earth complexes, including Ce^(3+), Eu^(2+), Yb^(2+) and Sm^(2+) complexes, and preliminarily summarizes the influence of the molecular structures of complexes on the luminescence properties of d-f transition.
