PROCESS FOR DEPOSITING LAYERS BASED ON METAL OXIDES, SUBSTRATE PROVIDED WITH A ETCHED LAYER OBTAINED FROM SAID PROCESS AND METHODS OF MANUFACTURING LAYERS USING SAID DEPOSITION PROCESS IN THE DEPOSITION OF A LAYER AND IN THE INDUSTRY

摘要

Sol-gel process for depositing a metal oxide layer on a substrate comprises irradiating the sol layer on the substrate with ultraviolet (UV) radiation before gel formation by heat treatment. Process for depositing a continuous or discontinuous metal oxide layer on a substrate, especially a transparent substrate, comprises: (1) preparing a sol from at least one metal oxide precursor, at least one chelating agent/stabilizer and optionally at least one solvent and/or dopant precursor, (2) depositing a layer of the sol on at least part of one side of the substrate, (3) irradiating at least part of the sol layer with UV radiation, and (4) heat treating at least the part of the sol layer that has been UV-irradiated.
