Abstract
A niobium doped tin oxide coating is applied onto a glass substrate to produce a low emissivity (low E) glass. The coating can optionally be doped with both niobium and other dopant(s), such as fluorine. The low emissivity glass has properties comparable or superior to conventional low E glass with fluorine doped tin oxide coatings.
