Techniques are provided for making a coated article including an antibacterial and/or antifungal coating. In certain example embodiments, the method includes providing a first sputtering target including Zr; providing a second sputtering target including Zn; and co-sputtering from at least the first and second sputtering targets in the presence of nitrogen to form a layer including ZnZrNon a glass substrate. These layers may be heat-treated or thermally tempered to form a single layer including ZnZrO. In other examples, two discrete layers of Zn and Zr may be formed. The coating may be heated or tempered to form a single layer including ZnZrO. Coated articles made using these methods may have antibacterial and/or antifungal properties.

Method of making coated article having antibacterial and/or antifungal coating and resulting product

In certain example embodiments, a coated article includes a doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the doped zirconium oxide and/or nitride based layer to result in a doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer has been found to improve scratch resistance.

Heat treatable coated article with zirconium based layer(s) in coating

In certain example embodiments, a coated article includes a tungsten-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the tungsten-doped zirconium oxide and/or nitride based layer to result in a tungsten-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with tungsten has been found to improve scratch resistance.
