Abstract In order to improve the optical properties and coloration effect. Co(II) and La3+ doped TiO2 thin films were synthesized via a sol–gel, by using butyl titanate as precursor on the surface of ITO conductive glass substrate. Several techniques were used to characterize produces. Adopting the Sol-gel technology, [CH3(CH2)3O]4Ti, La2O3, CoCl2•6H2O as the precursor, the composite membranes with different molar ratio of Ti, Ti/La, Ti/Co to be prepared on the ITO glass substrate, the optimum technological parameters for preparation of the base material of the electro-induced discoloration glass are determined. The structure and surface morphology optical and electrochromic properties of Co(II) and La3+-doped TiO2 films were examined with X-ray diffraction (XRD) analysis, energy dispersive spectrometer (EDS), scanning electron microscopy (SEM), and ultraviolet-visible spectrophotometer (UV-vis) DTA-TG analysis. It was found that: The sintering temperature coating number, [CH3(CH2)3O]4Ti content of the TiO2 film sample, and the doping category are the main factors that affect the structure and properties of the membrane based material; Using two alcohol amine as chelating agent can effectively inhibit the formation of Ti (OH)4 precipitation; The properties of the TiO2 glass film prepared by La2O3 and CoCl2·6H2O are fine; Materials based on the preparation of a radiochromic film transmittance, high cyclic reversibility, cyclic voltammetry characteristics significantly, the results of the study for the electric induced radiochromic film-based material development and application provide a theoretical and experimental basis.
