ABSTRACT:
A coated glass substrate includes a glass substrate; and a metal oxide coating provided on the glass substrate, which metal oxide coating is a pyrolytically formed oxidized metal coating, includes a metal oxide layer whose metal constituents consist essentially of aluminum atoms and vanadium atoms in an amount ranging from about 2% to about 10% of the aluminum atoms, and has a refractive index of at least 1.67. Additionally, a coated glass substrate includes a glass substrate; a metal oxide undercoat which is provided on the glass substrate and which is a pyrolytically formed oxidized metal coating whose metal constituents consist essentially of aluminum atoms and vanadium atoms in an amount ranging from about 2% to about 10% of the aluminum atoms; and a tin oxide overcoat which is provided on the metal oxide undercoat and which is a pyrolytically formed tin oxide coating, wherein the metal oxide undercoat has an optical thickness selected to reduce reflected visible light optical interference effects due to the tin oxide overcoat. Such a tin oxide coated glass exhibits reduced iridescence and reduced interfacial haze from sodium ion migration.
