摘要
以3-巯基丙基三甲氧基硅烷和对巯基苯为偶联分子,在玻璃基底上进行了二维和三维金、银纳米粒子的组装,以扫描电镜表征并研究其紫外吸收光谱,结果表明,随着组装层数的增加,紫外峰位发生红移,说明层与层之间存在耦合效应。
Gold and silver nanoparticles were assembled in 2D and 3D on glasses by using 3-mercaptopropyl trimethoxysillane and 1,4-benzenedithiol as coupling molecule to study their UV spectrum.The results showed that ultraviolet peak moved to infrared peak with increasing of assembling layers.It illustrated that there was coupling effect between layer and layer.
