摘要
以无水碳酸钠作为碱和内核, 通过其与稀土铽离子及有机配体乙酰水杨酸(aspirin)反应得到了新型的铽配合物复合碳酸钠核壳荧光材料。荧光显微图像表明该复合荧光材料具有明亮的绿色荧光, 发射光谱显示有铽离子的特征发射峰。材料的激发光谱随着碳酸钠用量的改变而发生变化, 说明铽配合物在碳酸钠表面的结构并非是单一的, 会随着碳酸钠的用量而发生改变。复合材料的荧光强度随着碳酸钠用量的增多而呈现下降的趋势, 平均荧光寿命随着碳酸钠用量的增多呈现上升的趋势。
Abstract
Na2CO3 being used as the base and kernel, a new type of core-shell fluorescent material terbium complex was obtained by reaction of it with terbium and organic ligands acetylsalicylic acid (aspirin). The fluorescence micro images show that the composite materials emit bright green fluorescence which attribute to the emission of terbium ion. The excitation spectra shapes of the composite materials change with the varying of amount of sodium carbonate, demonstrating that the structures of terbium complexes on the surface of sodium carbonate are different. The fluorescence intensity of the composite material shows a downward trend with the increasing of the amount of sodium carbonate, and the average fluorescence lifetime shows an upward trend.
