Window with anti-bacterial and/or anti-fungal feature and method of making same
First Claim
1. A coated article including a coating supported by a glass substrate, the coating comprising:
- a layer comprising silver on the glass substrate;
a layer comprising zirconium oxide (ZrxOy), where y/x is from about 1.2 to 2.5, on the glass substrate over at least the layer comprising silver;
a photocatalytic layer comprising an anatase oxide of titanium on the glass substrate over at least the layer comprising silver and the layer comprising zirconium oxide; and
wherein each of the layer comprising zirconium oxide and the photocatalytic layer comprising the anatase oxide of titanium are porous so as to permit silver from the layer comprising silver to migrate and/or diffuse to the outwardmost surface of the coated article over time.

Abstract
Certain example embodiments of this invention relate to a window having anti-fungal/anti-bacterial properties and/or self-cleaning properties, and a method of making the same. In certain example embodiments, a silver based layer is be provided and the layer(s) located thereover (e.g., the zirconium oxide inclusive layer) are designed to permit silver particles to migrate/diffuse to the surface over time to kill bacteria/germs at the surface of the coated article thereby creating an anti-bacterial/anti-fungal effect. In certain example embodiments, silver may also or instead be mixed in with other material as the top layer of the anti-bacterial coating.
