摘　　要：采用传统的高温熔融法制备CdS纳米晶体掺杂铅硅酸盐玻璃。结构分析表明,因基础玻璃中PbO含量不同,导致热处理后析出的纳米晶体种类不同;电极化处理诱导了CdS掺杂玻璃样品阳极面非线性层中偶极子的取向排列和正交型CdS晶体的结构变形,进而有利于该样品二次谐波的产生。CdS nanocrystal doped glasses were prepared with conventional fusion method. Structural analysis shows that different kinds of nanocrystals precipitate with different contents of PbO in the base glass after heat treatment. The dipole reorientation and structural distortion of orthogonal CdS nanocrystal in the nonlinear layer around the anodic side are induced by the electric/thermal poling method, and the second harmonic is generated in the glass samples.
