Abstract: A method for producing a transparent, electrically conductive coating onto a substrate. The method includes the steps of (a) providing an ionized arc nozzle which includes a consumable electrode, a non-consumable electrode, and a working gas flow to form an ionized arc between the two electrodes, wherein the consumable electrode provides a metal material vaporizable from the consumable electrode by the ionized arc; (b) operating the arc nozzle to heat and at least partially vaporize the metal material for providing a stream of nanometer-sized metal vapor clusters into a chamber in which the substrate is disposed; (c) introducing a stream of oxygen-containing gas into the chamber to impinge upon the stream of metal vapor clusters and exothermically react therewith to produce substantially nanometer-sized metal oxide clusters; and (d) directing the metal oxide clusters to deposit onto the substrate for forming the coating.
