The effect of nanometer size of porous anodic aluminum oxide on adsorption and fluorescence of tetrahydroxyflavanol.
Nanoporous anodic aluminum oxide, which was obtained by two-step electrochemical anodization aluminum process, showed strong physical adsorption capability of tetrahydroxyflavanol (THOF). The fluorescence peak of THOF was also dependent on its environment because the surrounding electron field affected the molecule luminescence in nanoporous alumina. The effect of nanometer size on adsorption and fluorescence of THOF is observed. The mechanism is primarily discussed.
