制备了纳米铽-环丙沙星-邻菲啰啉稀土配合物,通过元素分析、热重差热分析、X射线衍射(XRD)、红外光谱、紫外光谱对配合物的组成、结构进行了表征,研究了配合物溶解性、热稳定性、发光性能和邻菲啰啉第二配体加入对铽-环丙沙星体系荧光性质的影响。荧光光谱的研究表明,环丙沙星通过分子内能量传递将部分能量传递给铽离子,同时邻菲啰啉的加入能有效地增强铽离子发光强度,配合物具有良好的发光性能,在紫外光激发下显示出Tb3+的特征发射峰,发出很强的绿色荧光。
The terbium - ciprofloxacin - phenanthroline rare earth complexes were prepared and the composition and structure of the complexes were characterized by elemental analysis, TG - DTA, XRD, IR and UV spectra The effects of complex solubility, thermal stability, luminescent properties and the addition of the second ligand of phenanthroline on the fluorescence of terbium-ciprofloxacin system were investigated. Fluorescence spectroscopy studies show that ciprofloxacin can transfer part of energy to terbium ion via intramolecular energy transfer, meanwhile, the addition of phenanthroline can effectively enhance the luminescence intensity of terbium ion. The complex has good luminescence properties. Under UV light Excited to show the characteristics of Tb3 + emission peak, emitting a strong green fluorescence.
