title: The fluorescence of Mg-Al-Eu ternary layered hydroxides response to tryptophan.
abstract: We have studied the fluorescence of Mg-Al-Eu ternary layered hydroxides (TLH) quenched by tryptophan (Trp). IR spectroscopy was used to evaluate the change of Trp structure which was caused by TLH. XRD and TG-DTA results further suggested a structural change of Trp after being reacted with TLH. XPS characterization confirmed a strong chemical reaction between Trp and TLH. These studies may present more direct evidence to explain the interrelation between the structural change of Trp and the fluorescent quenching of TLH.
