Abstract
A coated glass article includes a glass substrate and a pyrolytic coating deposited over the glass substrate. The coating includes a first inorganic metal oxide layer deposited over a major surface of the glass substrate. The first inorganic metal oxide layer includes titanium dioxide or tin oxide, has a refractive index of 1.8 or more, and is deposited at a thickness of 40 nm or less. A second inorganic metal oxide layer is deposited directly on the first inorganic metal oxide layer. The second inorganic metal oxide layer includes silicon dioxide and has a refractive index of 1.6 or less. A third inorganic metal oxide layer is deposited directly on the major surface of the glass substrate. The third inorganic metal oxide layer comprises silicon dioxide. The first inorganic metal oxide layer is deposited directly on the third inorganic metal oxide layer. The coated glass article exhibits a total visible light reflectance of 6.5% or less.
