© 2019 Bulgarian Academy of Sciences, Union of Chemists in Bulgaria.Zinc oxide films doped by Ce4+ (0.1 – 1 molar %) were for the first time obtained by sol-gel technique and their spectral luminescent properties on monocrystalline silicon supports were studied with the aim to develop sensitive surfaces for biosensor devices. It was found that adding Ce4+ enhances the ultraviolet luminescence (UVL) of ZnO films by a factor of 7 (0.7 % mass Ce4+). Films structures were controlled by SEM. Changes in UVL (ex = 280 nm, em = 356 nm) of ZnO and ZnO-Ce4+ films were investigated under the action of bovine myoglobin (10-8 – 10-12 M, deposited on the film surface by a spin-coating method).
