Figure 1: Dependences of efficiency factors of absorption (solid), scattering (dashed), and extinction (dashed-dotted) of radiation and parameter (dotted) for (1), (2) s for Au NPs with radii ((a), (e), and (i)), 25 ((b), (f), and (j)), and 50 ((c), (g), and (k)) nm, and the dependences of parameter ((d), (h), and (l)) for Au NPs with radii  nm (1),  nm (2), and  nm (3) on wavelengths . Au NPs are placed in silica ((a)–(d)), water ((e)–(h)), and air ((i)–(l)).
