• were added to the dichroic solution at 50 °C to reach a final concentration of 0.1% (w/w) of AuHCl4 in PVA (8.5 g PVA per 100 mL of 0.25 mM HAuCl4 solution), taking in account that the maximum solubility of PVA in water is ≈20% (w/w). A temperature below 50 °C produces less foam while gently stirring

• very small amorphous Si particles form while larger crystalline Ag particles are able to form. No intermixing occurs as Si has an extremely low solubility in Ag (the maximum solubility being 4 × 10–4 at % at 1623 K [20]). Due to van der Waal interactions, the particles agglomerate. As the relative size
