Abstract

We report a wet-chemical method to make films by spontaneous assembly of passivated Ag nanoparticles at the organic-aqueous liquid interface. The interfacial films exhibit a blue opalescence and are characterized with transmission electron microscopy and UV-vis spectrophotometry. Measurements indicate that nanoparticles in the interfacial film can form superlattices and in some cases nanostructures.

摘要

我们报道了一种通过在有机-水液体界面自发组装钝化银纳米颗粒来制备薄膜的湿化学方法。界面薄膜呈现出蓝色乳光，并通过透射电子显微镜和紫外-可见分光光度法进行表征。测量结果表明，界面薄膜中的纳米颗粒可以形成超晶格，在某些情况下还能形成纳米结构。
