摘要
通过阳极氧化法制备的孔径约 2 0~ 1 5 0 nm的多孔氧化铝纳米材料 ,表现出较强的吸附性能 ,主要利用物理吸附在纳米孔中填入有机荧光小分子姜黄素 ,与溶液中的发光现象相比 ,观察到了姜黄素的光谱蓝移现象 。
Nanoporous anodic aluminum oxide,which was obtained by a two step electrochemical anodization aluminum process,showed strong physical adsorption capability of curcumin.The fluorescence peak of curcumin was also dependent on its environment because the surrounding electron field affected the molecule luminescence in nanoporous alumina.The effects of nanometer size on adsorption and fluorescence of curcumin was observed.
