Preparation and Stability of Template-Synthesized Metal Nanorod Sols in Organic Solvents.

Abstract

Gold and silver nanorods of diameter 40 and 90 nm, and having a variety of aspect ratios (length/diameter), were prepared using the template synthesis approach. The stability of these nanorod sol was monitored using visible absorption spectroscopy. For both the Au and Ag nanorods (in both solvents), sols prepared from the 90 nm-diameter nanorods were found to be less stable than sols prepared from the 40 nm-diameter nanorods. The addition of the polymeric stabilizers poly(vinylpyridine) or poly(vinylpyrrolidone) did not enhance the stability of these nanorod sols.
