A method for the production of an inorganic film on a substrate, the method comprising: (a) depositing a layer of nanoparticles on the substrate by contacting the substrate with a nanoparticle dispersion; (b) treating the deposited layer of nanoparticles to prevent removal of the nanoparticles in subsequent layer depositing steps; (c) depositing a further layer of nanoparticles onto the preceding nanoparticle layer on the substrate; (d) repeating treatment step (b) and deposition step (c) at least one further time; and (e) optionally thermally annealing the multilayer film produced following steps (a) to (d); wherein the method comprises at least one thermal annealing step in which the layer or layers of nanoparticles are thermally annealed. |
