Table 1
Data for In, Ag, Al, Ag-In and Ag-Al (Wigner-Seitz radii (rs), surface energies (Es), LSPR wavelengths (λLSPR) and energies (ELSPR) of a sphere in a porous silica matrix (εm ≈ 2.17) in the dipolar approximation) and crystallographic properties of pure metals, Ag-In and Ag-Al alloys and oxides. All the corresponding references are indicated in the table. BCT, HCP, SC, FCC stand for body-centred tetragonal, hexagonal-closed packed, simple cubic, face-centred cubic lattices, respectively.
