Research Abstract

In this work, synthesis of ultrasmall gold nanorod with a subnamometer-sized diameter had been explored and a nobel gold nanorod with a pencil-like structure was obtained. This showed an intense absorption band in visible region and the correlation between the geometric structure and the absorption property was investigated both experimentally and theoretically.
