Patent ID: 8841164

Claim:
A liquid phase process for producing an indium oxide-comprising layer, the process comprising, in an anhydrous atmosphere: (a) applying an anhydrous composition comprising an indium halogen alkoxide and a solvent or dispersion medium to a substrate, to obtain an intermediate layer; (b) irradiating the intermediate layer with electromagnetic radiation of wavelength ≦360 nm, to obtain an irradiated layer; (c) optionally drying the irradiated layer; and (d) thermally converting the irradiated layer to an indium oxide-comprising layer, wherein the indium halogen alkoxide in the anhydrous composition has a formula (I): InX(OR) 2 (I), wherein: R is at least one selected from the group consisting of an alkyl radical and an alkoxyalkyl radical; and X is F, Cl, Br, or I.
