摘要

Highly crystalline gold nanoribbons have been synthesized via a simple method by L-cysteine reduc-tion of aqueous chloroaurate ions at room temperature, without additional capping agent or surfactant. Based on transmission electron microscopy (TEM) and UV-vis absorption studies for the intermediate products, the formation of gold nanoribbons is regarded as a kind of oriented attachment growth.
