Abstract
A method is provided for making a coated article including an anti-bacterial and/or anti-fungal 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 to form a layer comprising ZnxZryOz on a glass substrate. A coated article having an anti-bacterial and/or anti-fungal coating made using this method may also be provided.
Claims23
A method of making a coated article, the method comprising:
- providing a first sputtering target comprising Zr;
- providing a second sputtering target comprising Zn;
- and
- co-sputtering at least the first and second sputtering targets to form a layer comprising ZnxZryOz on a glass substrate, wherein the layer comprises from about 0.25% to 15% (atomic) Zn, from about 20% to 50% (atomic) Zr, and from about 40% to 80% (atomic) O.
A method of making a coated article, the method comprising:
- providing a first sputtering target comprising Zr;
- providing a second sputtering target comprising Zn;
- and
- sequentially sputtering from at least the first and second sputtering targets onto a glass substrate to form at least a first layer comprising Zr, and a second layer comprising Zn located directly on the first layer comprising Zr;
- and
- thermally tempering the glass substrate with said first and second layers thereon to form a coated article comprising a layer comprising zinc zirconium oxide with anti-bacterial and/or anti-fungal properties.
A method of making an anti-bacterial and/or anti-fungal coated article, the method comprising:
- sputtering Zn and Zr onto a glass substrate in the presence of at least oxygen;
- and
- forming a layer comprising ZnxZryOz on the glass substrate, wherein said layer comprises from about 0.25% to 15% (atomic) Zn, from about 20% to 50% (atomic) Zr, and from about 40% to 80% (atomic) O, and wherein the layer substantially inhibits the growth of bacteria and fungi.
A method for making a coated article, the method comprising:
- providing a first sputtering target comprising Zr;
- providing a second sputtering target comprising Zn;
- and
- co-sputtering from at least the first and second sputtering targets onto a glass substrate to form a layer comprising ZnxZryOz, wherein a different sputtering power is applied for each of the first and second targets in order to control the composition of the layer.
A method for making a coated article, the method comprising:
- providing a first sputtering target comprising Zr;
- providing a second sputtering target comprising Zn;
- and
- co-sputtering from at least the first and second sputtering targets to form a layer comprising ZnxZryOz on a glass substrate, wherein the first and second sputtering targets are offset from each other by an angle theta (θ) which is greater than zero degrees.
A method of making a coated article, the method comprising:
- providing a first sputtering target comprising Zr;
- providing a second sputtering target comprising Zn;
- and
- co-sputtering at least the first and second sputtering targets to form a layer comprising a nitride of Zr doped with Zn on a glass substrate, wherein the layer comprises from about 0.25% to 20% (atomic) Zn.
A coated article with anti-bacterial and/or anti-fungal properties, comprising:
- a layer comprising ZnxZryOz on a glass substrate, the layer having anti-bacterial and/or anti-fungal properties, and wherein said layer comprises from about 0.25% to 15% (atomic) Zn, from about 20% to 50% (atomic) Zr, and from about 40% to 80% (atomic) O.
