Europium-doped titanium dioxide/graphene oxide composite film and preparation method thereof
The invention discloses a europium-doped titanium dioxide/graphene oxide composite film and a preparation method thereof. According to the film, a substrate is provided with a europium-doped titanium dioxide nanodot and graphene oxide mixed layer, wherein titanium dioxide nanodots in the mixed layer are 30-150nm in size and 1.0*10<10>-1.0*10<11>/cm<2> in density, the molar concentration of Eu<3+> is 0.005-0.015mol/L, and the concentration of graphene oxide is 5-15mg/L. The preparation method is based on a sol-gel method and comprises the steps of preparing europium-doped titanium dioxide/graphene oxide precursor sol and then performing thermal treatment of the precursor sol on the substrate by a spin-coating method. The film provided by the invention has favorable biocompatibility, protein adsorption property and luminescence property, and can be used for in-situ semi-quantitative characterization of the protein adsorption capacity of a film surface. The film can be applied in the biomedical engineering fields of cell culture in vitro, tissue engineering and the like.
