Abstract: The silicon oxide film was coated on the bottom ( tin) surface of 3 mm thick float glass by sol-gel method .The silicon oxide film was embedded with Ag nanoparticles , so that it can achieve the effect of blue light absorption .The zinc oxide film with wurtzite structure was coated on the non-tin surface to achieve the barrier of ultraviolet effect .The effect of heat treatment temperature and film thickness on the near UV and blue light barrier rate was also studied .The result shows that the film is more compact with the increase of annealing temperature .Meanwhile , The absorption rate of blue light also increases gradually , and the absorption peak shifts red .The structure of the silicon oxide film can absorb short wave blue light of 380-450 nm by the reduction of AgNO3 into Ag nanoparticles on tin rich surface .The experimental samples show a bright golden yellow color , and the degree of gold gradually deepened with the increase of film thickness .The Zinc Oxide film shows a stable wurtzite structure with a film thickness of 438 nm, and the surface shows particle state .The UV light ( <380 nm) barrier rate of sample a is 98.83;.The surface of the silicon oxide film is compact with the thickness of 200 nm, and the barrier rate of 380 nm to 450 nm is 90 .73;.The visible light transmittance of the sample from 450 nm to 780 nm can reach 77 .8;.
