Window with UV-treated low-E coating and method of making same

Abstract

Certain embodiments of this invention relates to a coated article including 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. The low-E coating includes at least one infrared (IR) reflecting layer of or including silver which is located on and directly contacting a contact/seed layer of or including metal oxide such as zinc oxide and/or zinc stannate. 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 the contact/seed layer which in turn transfers the heat energy to the adjacent IR reflecting layer. This heating of the silver inclusive layer improves the silver layer's electrical, optical and/or thermal blocking properties. The UV treated coated article, with its improved properties, may be used in the context of monolithic or insulating glass (IG) window units.
