| Abstract: | The fluorescence quenching of Ce3+ ions in an aqueous solution of cerium nitrate with colloidal graphene oxide (GO) was studied. By measuring the relative fluorescence intensities and the lifetimes of the excited states of these ions from the concentration of GO plates and using the Stern-Volmer equations, it was shown that electron excitation of Ce3+ is accompanied by static fluorescence quenching. The measured Stern–Volmer association constant of aquacomplexes of cerium with GO amounts to 24.7 l/g, which is significantly lower than the constants of cationic dyes of rhodamines and metal cations. The result is explained by the presence of negative charges on the surfaces of the interacting particles |
