摘　　要：采用溶胶 凝胶法在二氧化硅玻璃基底上制作了硅酸铅玻璃薄膜,并对不同波长的紫外光照射后硅酸铅玻璃薄膜的吸收光谱进行了研究.结果表明,硅酸铅玻璃在235nm附近的吸收峰受308nm和266nm的紫外光照射后没有变化,但受248nm的紫外光照射后吸收峰出现了光漂白现象.The lead silicate glass films were fabricated by sol-gel method.The absorption spectra of these lead silicate glass films were studied after irradiation with different wavelength UV laser.Regarding the absorption peak of lead silicate glass near 235 nm no change can be found after 308 nm and 266 nm UV laser irradiation.But after irradiation with 248 nm UV laser,this peak is bleached.
