1. A method of forming an anatase titanium dioxide coating on a substrate, comprising:
- providing a substrate;
forming at least one barrier layer on the substrate;
preparing a titanium dioxide sol-gel composition;
coating the at least one barrier layer with the sol-gel composition; and
heating the coated substrate to form an anatase titanium dioxide coating.

Abstract
Methods for forming titanium dioxide coatings are disclosed. At least one barrier layer is formed on a substrate. Sol-gel compositions are prepared and coated on the at least one barrier layer, and heated at a temperature sufficient to form an anatase titanium dioxide coating. Titanium dioxide coatings having at least one of improved visible light transmission properties, reflective properties, and/or haze are also disclosed.
