Figure 6From: Shape-tailoring and catalytic function of anisotropic gold nanostructures UV-vis-NIR absorption spectra of AuNPs. UV-vis-NIR absorption spectra of AuNPs observed during the reaction of Au salt (0.4 mM) with detergent (1 wt.%) at different temperature. The inset shows the photographs of the different nanoparticle solutions with color changes during the formation of AuNPs as a function of temperature.Back to article page
