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.
