The present invention relates to coating glass for architectural or automotive use, either monolithic or laminated, having solar control properties. The coating consists of several layers of different metal oxide semiconductors (TiO.sub.2, ZnO, ZrO.sub.2, SnO.sub.2, AlO.sub.x) and a layer of metallic nanoparticles, which when superimposed on a pre-established order give the glass solar control properties. In particular the use of protective layers of n-type semiconductors around the metallic nanoparticles layer. It also relates to the method for obtaining the coating by means of the aerosol-assisted chemical vapor deposition technique, using precursor solutions containing an organic or inorganic salt (acetates, acetylacetonates, halides, nitrates) of the applicable elements and an appropriate solvent (water, alcohol, acetone, acetylacetone, etc.). The synthesis is performed at a temperature between 100 and 600° C. depending on the material to be deposited. A nebulizer converts the precursor solution into an aerosol which is submitted with a gas to the substrate surface, where due to the temperature the thermal decomposition of the precursor occurs and the deposition of each layer of the coating occurs.

Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer. Electrical busbars and micro-nano electrical grids may be integrated with one or more metal layers to provide functionality such as de-icing and defogging.
