荧光黄阴离子插层镁铝水滑石的合成、表征及光学性能研究

摘要

以CO32-型镁铝水滑石为前体,以有机荧光黄阴离子为客体,采用焙烧复原法和离子交换法,组装得到有机阴离子柱撑水滑石功能材料.并用FTIR、XRD、TG-DSC和分子荧光光度计等手段对样品进行了表征,发现该功能材料的荧光发射波长发生蓝移(约10nm),且其发光强度比荧光黄明显减弱,表明该功能材料能有效调控有机阴离子的荧光性能.%The function material was made by calcined method and ion exchanged method, using CO32- type Mg, Al-hydrotalcite as precursor ar fluorescein anion as object. The samples were characterized by XRD, FTIR, TG-DSC and Fluorometry. As a result, the emission wave of the Fluoresce moved to low wave, and the intensity became weak. It showed that the function material could regulate the fluorescence of the organic anion.
