Abstract
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.
