Highly stable photoluminescent (PL) nanocomposite multilayers including quantum dots (see picture) were prepared using a nucleophilic substitution reaction. The assembly of functional nanoparticles in a nonpolar solvent can allow selective deposition and induce a hydrophobic surface with a water contact angle above 115°, which significantly enhances the PL durability of nanocomposite films.
