    • Abstract

       

      The photosensitization of colloidal ZnO nanoparticles with riboflavin (RF) was investigated using absorption, fluorescence spectroscopic measurements and time resolved fluorescence measurements. Riboflavin adsorbed strongly on the surface of ZnO nanoparticles. Apparent association constant was obtained from the fluorescence quenching measurements. The free energy change, 𝛥𝐺et, for electron transfer process has been calculated by applying Rehm Weller equation.
