Supporting Information
In the Supporting Information, more Ψ and Δ ellipsometric images (Figure S1 and Figure S2) recorded during the annealing of a 380 nm thick Au3+-doped PVA film (doping level 2% w/w) are given. Theoretical optical properties of Au–PVA nanocomposites are given in Figure S3. The properties were calculated using the Maxwell–Garnett approximation, assuming a spherical shape for the NPs (depolarisation factor equal to 1/3). Details of the Ψ and Δ maps after annealing in Figure 7 (bottom images) are given in Figure S4.
