摘　　要：采用溶胶 -凝胶法成功地制备出SnO2 微晶掺杂SiO2 玻璃薄膜。通过X射线粉末衍射和晶胞常数计算确认了SnO2 纳米微晶均匀分布于玻璃基质中 ;由薄膜的室温透射光谱研究发现 ,随热处理温度的升高、热处理时间的延长 ,薄膜的透射光谱向长波方向移动 ,表现出明显的量子尺寸效应。SnO 2 microcrystallite doped films on silica glass were prepared successfully by sol-gel process.The SnO 2 microcrystallites in the glass medium were confirmed by means of XRD and the calculation of crystal lattice constant.Transmission spectra of the films at room temperature showed that the transmission valley shift toward longer wavelength not only with the increase of heat-treatment time and temperature.Such shift is the evidence of quantum size effect in the glass.
