Fig. 4 — Experimentally obtained and calculated diameters of AuGa₂ NCs, as prepared from various sizes of initial Au seeds (A) and corresponding TEM images (B to G). The shaded area in (A) illustrates the increase of NC size upon amalgamation reaction (note a good agreement between predicted and measured size of AuGa₂ NCs). (H) A comparison between size distribution histograms of initial seeds (Ag, Cu, Ni, Au, and Pd) and corresponding IMC NCs (Ag₃Ga, Cu₂Ga, Ni₂Ga₃, AuGa₂, and PdGa) reveals the preservation of size dispersion characteristics (polydispersity percentages are given next to histograms) upon amalgamation.
