Abstract

The growth of a single gold nanorod attached to a coverslip is observed in real time through supercontinuum dark field spectroscopy. The scattered light is collected with a high magnification lens. As reported on page 3743 by L. O. Herrmann and J. J. Baumberg, the frequency shift of the localized surface plasmons in the rod due to deposition of gold ions at the nanorod caps reveals quantitative information about its growth kinetics.
