摘要：合成了乙酰基丙酮(AcAc)和二苯甲酰基甲烷(DBM)的水合二元铒配合物以及乙酰基丙酮、二苯甲酰基甲烷和三氟乙酰基丙酮(TFA)分别与1,10-邻菲罗啉(Phen)的三元铒配合物，并经元素分析确认;表征了配合物的紫外-可见吸收光谱和红外吸收光谱;探讨了铒配合物的近红外发光性能，并对不同配体对发光性能的影响进行分析比较。结果表明Er(AcAc)₃Phen三元配合物是所研究的几种配合物中近红外发光性能最优的。

Abstract：Several erbium organic complexes, hydrated erbium binary complexes with acetylacetone (AcAc) or dibenzoylmethane (DBM), erbium ternary complexes derived from 1,10-phenanthroline (Phen) with acetylacetone (AcAc), dibenzoylmethane (DBM) or trifluoroacetylacetone (TFA), were synthesized and identified by elemental analysis. The UV-Vis absorption and FTIR spectra measurements have been employed for all the erbium complexes. Near infrared (NIR) photoluminescence properties, such as luminescence intensity and effective bandwidth, of the erbium complexes were also studied. As a result, the erbium ternary complex with AcAc and Phen exhibits the most excellent luminescence properties among those investigated complexes.

Key words：Erbium organic complex;NIR photoluminescence;Spectroscopic characterization
