Abstract:
A coated, solar control glass having preselected reflected color and having a NIR solar absorbing layer and a low emissivity layer, comprising glass having a SnO.sub.2 coating containing at least two layers with one layer being a solar absorbing layer comprising SnO.sub.2 containing a dopant selected from the group consisting of antimony, tungsten, vanadium, iron, chromium, molybdenum, niobium, cobalt, nickel and mixtures thereof and another layer being a low emissivity layer comprising SnO.sub.2 containing a dopant selected from the group fluorine, phosphorus, and mixtures thereof wherein the thickness of the solar absorbing layer is from 80 to 300 nanometers (nm) and the thickness of the low emissivity layer is from 200 to 450 nm, the reflectance of visible light from the coated side of the glass is 6.2% or greater and said preselected reflected color is achieved without the need for a separate iridescence reflected color suppressing layer.
