摘　　要：用ｓｏｌ－ｇｅｌ法在玻璃表面制备了含银纳米粒子的二氧化硅薄膜．拍摄了银粒子的ＴＥＭ照片．在室温下用拉曼光谱仪测定了样品的光致发光谱．研究了样品的光致发光强度与纳米银的掺杂量、镀膜时的提拉速度和热处理温度之间的关系．Nanosized silver particles embedded silica films were prepared on float glass by the sol-gel process. The TEM photograph of Ag particles was taken, and the photoluminescence spectra of samples were measured at room temperature. The dependence of luminescent intensity on quantity of silver doping and drawing speed and thermal treatment temperature was investigated.
