摘要
采用液 液二相转移方法合成出颗粒直径为 (4 .18± 0 .5 )nm的银纳米粒子溶胶 ,并用紫外 可见光谱对所制得的银纳米粒子溶胶的单分散性和稳定性进行了研究 .结果表明 ,所得到的溶胶相为稳定的、粒径分布窄的单分散体系 .红外光谱的分析结果表明 ,稳定剂 1 壬基硫醇包缚在银纳米粒子表面 .并且 。
The silver nanoparticles of (4.18 +/- 0.5) nm in diameter were prepared using two-phase Liquid-liquid method. The size distribution and the stability of the silver nanoparticles were studied by the UV-vis spectrum. The results showed that the silver colloid solution was stable and monodispersed. The IR spectra indicated that the nanoparticles were capped by 1-nonanethiol. Two-dimensional ordered structure of the nanoparticles was formed by self-assembly technique.
