复合膜中纳米银粒子的光吸收特性研究

摘要

本文通过溶胶凝胶法，制备出金属纳米银粒子复合膜.电镜(TEM)测量结果表明，复合膜中所掺入的银粒子尺寸属纳米量级.实验测出了复合膜中银粒子的吸收光谱，与其在银胶中吸收谱相比，发现其吸收峰红移52.5nm.并对测试结果进行了细致分析.%In the paper ,we reported composite film of silver nano-particles prepared via the Sol-Gel technique and its measurements of the optical absorption. The TEM photograph of composite film showed that silver particles size was nanoscale. The absorption peak of silver nano-particles in composite film yield red-shift as compared with silver nano-particles in colloidal solution. The results were analyzed and discussed in detail.
