The preparation of CeO_2 UV-shielding film by sol-gel process

CeO2 ultraviolet absorber film was produced by collosol method and gelatin method on the ordinary glass substrate.The different ratio layers of ultraviolet absorber film produced by intersect coating-method with TiO2 membranous layer as the cushion.By the experiment results,it is distinct that the transmissivity of ultraviolet rays and visible light by the different ratio layers,within a certain range,the absorption rate of ultraviolet rays increased with the addition of concentration CeO2-collosol.Moreover,It is neglectful that the assembly time of collosolon affects the absorptivity of ultraviolet absorber film.
