| 摘 要： | 采用溶胶-凝胶法,在3 mm厚的普白玻璃含锡面镀制镶嵌Ag纳米粒子的氧化硅薄膜,达到吸收蓝光的效果,在其非锡面镀制纤锌矿结构的氧化锌薄膜,达到阻隔紫外效果.通过双膜层的相互作用,达到对紫外和短波蓝光有效阻隔吸收,从而获得具有紫外蓝光防护及润眼功能的镀膜玻璃.研究了热处理温度和膜层厚度对近紫外和蓝光阻隔率的影响.结果表明:随着退火温度的升高,膜层更加致密,且退火温度越高,蓝光的吸收率也逐渐提高,吸收峰位红移.利用浮法玻璃本体的富锡表面还原AgNO3成Ag纳米粒子分散镶嵌在氧化硅薄膜的结构,能有效吸收380～450 nm的短波蓝光.实验样品呈现出美观的淡金黄色,且随着膜厚的增大,金黄色程度逐渐加深.以样品a为例,所制备的氧化锌膜层为稳定的纤锌矿结构,膜厚为438 nm,表面为球状颗粒,对380 nm以下的紫外光阻隔率为98.83;;所制备氧化硅薄膜厚为200 nm,表面致密,对380～450 nm的蓝光阻隔率为90.73;,样品整体450～780 nm可见光透过率为77.8;.

| 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;. |
