Abstract

F1or the gold nanorods synthesis by seed-mediated method, the overgrowth goes against the shape controlling for the final product. Here, through optimizing the growth solution condition, the nanorods shape could be tuned effectively by just adjusting the seed amount introduced initially. Further, the growth-stop experiment reveals that the final nanorods with different shapes have a similar size parameter at their respective turning points (TP) of the overgrowth process, indicating that all nanorods in solution grow following a common morphology evolution trajectory but terminate at different points, which have certain aspect ratio. Additionally, the morphology evolution of gold nanorods could be simulated quantitatively using the classic chemical dynamic theory, which also opens a pathway to tune the aspect ratio of product accurately.
