First Claim
Patent Images
1. A method of making a coated article for use in a window, the method comprising:
- having a coated article including a glass substrate that supports a low-emissivity (low-E) coating comprising at least one layer comprising silver located directly on and contacting a contact layer comprising zinc oxide that can absorb ultraviolet (UV) radiation, the low-E coating further comprising a dielectric layer between the contact layer comprising zinc oxide and the glass substrate, and an upper dielectric layer located over the layer comprising silver so that the layer comprising silver is located between the upper dielectric layer and the glass substrate;
directing UV radiation from at least one UV source toward the coating and exposing the coating to UV radiation in order to reduce a sheet resistance of the coating and/or increase visible transmission of the coating; and
wherein the coated article has a visible transmission of at least about 50% after said exposing.

Abstract
A coated article includes a low-emissivity (low-E) coating supported by a substrate (e.g., glass substrate) for use in a window, where the low-E coating is exposed to ultraviolet (UV) radiation in order to improve the coating'"'"'s and thus the coated article'"'"'s electrical, optical and/or thermal blocking properties. Exposing the low-E coating to UV radiation, e.g., emitted from a UV lamp(s) and/or UV laser(s), allows for selective heating of a contact/seed layer which transfers energy to the adjacent IR reflecting layer.

14. A method of making a coated article for use in a window, the method comprising:
-
having a coated article including a glass substrate that supports a low-E coating comprising at least one substantially metallic layer comprising silver located directly on and contacting a contact layer comprising zinc oxide that has a bandgap of from 3.2 to 3.4 eV, the low-E coating further comprising a dielectric layer between the contact layer comprising zinc oxide and the glass substrate, and an upper dielectric layer located over the layer comprising silver so that the layer comprising silver is located between the upper dielectric layer and the glass substrate; directing UV radiation from at least one UV source toward the coating and exposing the coating to UV radiation in order to reduce a sheet resistance of the coating and increase visible transmission of the coating; and wherein the coated article has a visible transmission of at least about 50% after said exposing. - View Dependent Claims (15, 16)
