series of lanthanide metal complexes [Ln = Sm (1 and 5), Eu (2 and 6), Tb (3 and 7), Er (4 and 8)] were synthesized with imidazole-containing β-diketone ligands. Complexes 1–8 were characterized by IR, elemental analysis, powder XRD, and TG measurements. The photoluminescence properties and the probable mechanism of the Sm, Eu, and Tb complexes were studied. The Eu complex gener-
一系列镧系金属配合物[Ln = Sm (1 and 5), Eu (2 and 6), Tb (3 and 7), Er (4 and 8)] 用含咪唑的β-二酮配体合成。通过红外、元素分析、粉末 XRD 和 TG 测量对配合物 1-8 进行了表征。研究了Sm、Eu和Tb配合物的光致发光特性和可能的机理。Eu 络合物生成
