摘要: 本论文利用溶剂热反应，以乙二胺为结构导向剂合成了一种三维稀土发光材料。结构分析表明化合物属三斜晶系，空间群均为P-1，a = 5.0050(5) Å，b = 7.3930(5) Å，c = 11.7210(5) Å；α = 89.981(5)˚，β = 83.593(5)˚，γ = 89.880(5)˚，V = 431.0(6) Å3，化合物的三维结构是由SO42- 连接左旋的L-[-Eu-O-]n链和右旋的R-[-Eu-O-]n螺旋链构筑而成的，化合物展现了强的荧光性质。
Abstract: A new 3D rare earth luminescent material [Eu(SO4)F·H2O], has been synthesized under solvo-thermal conditions by using ethylenediamine (en) as the structure directing agent (SDA). The co-lorless block crystals were characterized by IR, TGA and ICP. The structure of compound 1 was determined by single-crystal X-ray diffraction [Triclinic, P-1, a = 5.0050(5) Å, b = 7.3930(5) Å, c = 11.7210(5) Å; α = 89.981(5)˚, β = 83.593(5)˚, γ = 89.880(5)˚, V = 431.0(6) Å3]. Crystal structure analysis shows that the 3D framework of compound 1 is constructed from the left-handed and the right-handed helical channels which are connected by SO42- groups using 6-membered rings and 4-membered rings. Compound 1 represents a strong luminescence upon the excitation.
