Histograms of the photomodification factor (μ) of Ag dimer vs. the average particle size ⟨R⟩ and the degree of polydispersity for various thicknesses of the particle adlayer h_i: (a), (d) 0.65 nm; (b), (e) 1.3 nm; (c) 1.8 nm; light intensity I: (a)–(c) 4.26 × 10⁸ W/cm²; (d), (e) 1.06 × 10⁸ W/cm²; pulse duration τ_p = 20 ps, in 20 ns after the pulse end. Tone scale corresponds to the values of μ.
