Patent number: 9487438Abstract: The present invention provides low-E thin film optical stacks with improved optical and infrared reflecting properties and methods of making the same. More specifically, the present invention provides for a metal oxide thin film coating that exhibits lower emissivity values than its predecessor due to the inclusion of an oxidizer in the metal oxide deposition process, such as a strong acid such as nitric acid. The present invention also provides for a method that increases the coating efficiencies of the thin films described herein.Type: GrantFiled: March 18, 2010Date of Patent: November 8, 2016Assignees: AGC FLAT GLASS NORTH AMERICA, INC., AGC GLASS EUROPE, S.AInventors: Christopher R.
