合成了铽的配合物[TbL](ClO_4)_3(L:2,2,2’,2’-四[N-苯基-N-苄基(乙酰胺)-2-氧甲基]丁醚),通过离子交换反应将配离子[TbL]~(3+)插层组装到蒙脱土(MMT)层板间,制备出了新型复合发光材料[TbL]~(3+)-MMT.用元素分析、X射线衍射、傅氏变换红外光谱和紫外-可见光谱对材料进行了表征,对其荧光性质进行了研究.结果表明,复合发光材料保持了蒙脱土良好的层柱结构特征和[TbL]~(3+)离子的笼状结构特征,[TbL]~(3+)离子以单层形式分布于蒙脱土层板间.在紫外光激发下,复合发光材料发出较强的绿色荧光,其发射光谱与相应配合物的发射光谱相似.与相应纯配合物比较,复合发光材料单位质量Tb~(3+)的相对荧光强度、荧光单色性和光稳定性有显著改善,其激发波长向可见光区发生明显位移,说明插层组装对相应配合物的激发波长有一定的调制作用.
Terbium complex [TbL] (ClO_4) _3 (L: 2,2,2 ’, 2’-tetrakis [N-phenyl-N-benzyl ), A novel composite luminescent material [TbL] ~ (3 +) - MMT was prepared by intercalation of ion [TbL] ~ (3+) into montmorillonite (MMT) Elemental analysis, X-ray diffraction, Fourier transform infrared spectroscopy and UV-Vis spectroscopy were used to characterize the material and the fluorescence properties were studied.The results show that the composite luminescent material has a good columnar structure characteristics of montmorillonite and [ TbL] ~ (3+), the [TbL] ~ (3+) ions are distributed in the monolayer between the montmorillonite layers, and under the excitation of ultraviolet light, the composite luminescent material emits a strong green Fluorescence and its emission spectra are similar to those of the corresponding complexes.Compared with pure complexes, the relative fluorescence intensity, fluorescence monochromaticity and photostability of Tb 3+ of the composite luminescent materials are significantly improved, Wavelength to the visible region of significant displacement occurred, indicating that the intercalation assembly of the corresponding complex excitation wavelength has a modulation effect.
