Abstract

For the first time, the interaction between morin and TiO(2) nanoparticles was investigated by UV-vis absorption, UV-vis diffuse reflectance spectrum, FT-IR, fluorescence, and three-dimensional fluorescence spectra techniques. The results showed that chemical bonds had formed between the surface atoms of TiO(2) nanoparticles and morin molecules. The fluorescence intensity of TiO(2)-morin nanocomposites was much higher than that of morin particles. In addition, the effect of TiO(2) concentrations on the fluorescence intensity of morin was also investigated.
