Figure 1: (a) corresponds to the absorption spectrum of B-GNPs and their Gaussian deconvolution. The continuous line corresponds to the Vis-NIR extinction spectrum of branched gold nanoparticles, while the next four curves correspond to the Gaussian deconvolution. The last curve represented by ▵ symbols corresponds to the sum of peaks one and two (★ and ). (b) corresponds to the absorption spectra of nanospheres and nanorods.
