通过控制包裹剂十六烷基三甲基溴化铵(CTAB)的浓度对纳米粒子的形貌进行调控。使用紫外一可见分光光度计和透射电镜等方法对合成的Ag纳米粒子进行表征。结果表明:CTAB的浓度对产物的形貌关系密切,通过调节CTAB的浓度可生成球棒混合、纳米棱镜和棱镜与纳米棒的混合形貌。
The effects of the concentration of coating agent cetyltrimethyl ammonium bromide (CTAB) were investigated and samples were characterized and analyzed by UV-visible spectrophotometer and the transmission electron microscope (TEM). Results indicated that the change of CTAB concentration could lead to obvious changes of the nanopartiele morphologies as mixture of nanosphere and nanorods, nano- prism, and mixture of nanoprism and nanorods.
