Apart from silver, gold is also largely employed in the field of plasmonics especially because of its ability to absorb in the visible and NIR regions. Figure compares the plasmonic activity of this noble metal with respect to silver by depicting the UV/vis photoabsorption spectra of 4 silver/gold tetrahedral alloys of 120 atoms, i.e. Ag 120 , Ag 100 Au 20 , Ag 20 Au 100 and Au 120 . Building on a full tetrahedral silver structure, they are constructed such as the number of gold atoms increases along the altitude. Due to the similar behaviors analyzed for the global (range-separated) hybrids investigated herein, in the following, we will only discuss the spectral features computed by their PBE0 (RSX-PBE0) representative.
