Abstract
The effect of solution volume covariation on the growth mechanism of Au nanorods synthesized using a seed-mediated method was studied. The results from the ultraviolet–visible absorption spectra of gold nanorods (GNRs) revealed that the transverse surface plasmon resonance was ∼550nm for all GNR samples synthesized in various total volumes of growth solutions. The wavelength of longitudinal surface plasmon resonance of GNRs increased from 757 to 915nm, with the total volume of growth solution being raised from 10 to 320ml. Moreover, the calculated aspect ratio (AR) also increased from 3.55 to 5.21 while the total volume of growth solution increased from 10 to 320ml. Transmission electron microscopy microstructures showed that the growth mechanism of GNRs along 〈100〉 is in accordance with the hypothesis that the ratio of the number of monodispersed Au atoms existing in the growth solution to the number of seeds explain the behavior of Au atoms deposited on the nanorods with respect to all of the constituent concentrations in the growth solution on the AR of GNRs.
