| Abstract: | The colloidal coating solution of amorphous state was prepared via metal alkoxides of TiO2 and SiO2 producing hydrolysis in alcoholic solution. Then by dipping process TiO2/SiO2 dielectric multi-films were deposited from the solution. The advantege of the method is low production cost and simple film-coating epuipment and technology. The solution prepareing coating technology and the structure of the films were studied. The relation of the thickness of films vs concentration of solutions and lifting speeds were presented in compliance with the experimental results. The change of film thickness with baking temperature was described, and the surface structure of the films with -SEM was also analysed. |
