Abstract: The invention relates to a coated glass pane with a low-e and/or solar controlcoating comprising—in sequence from the glass surface—at least the following layers: —a lower anti-reflection layer, comprising: a base layer of an (oxi)nitride of aluminum, a middle layer of an oxide of Zn and Sn, a top layer of a metal oxide; —a silver-based functional layer; —a barrier layer; —an upper anti-reflection layer comprising a layer of an (oxi)nitride of aluminum 10 having a thickness of more than 10 nm.

Abstract: The invention relates to a coated glass pane with a low-e and/or solar control coating comprising at least one layer sequence which comprises at least the following transparent layers: a lower anti-reflection layer, an IR-reflecting layer, an upper anti-reflection layer. At least one of the anti-reflection layers comprises at least one compound layer containing a mixture of an (oxy)nitride of Si and/or Al and of ZnO. The inventive coated glass panes are preferably heat treatable, e.g. toughenable and/or bendable.

Abstract: A process for the production of a coated substrate, preferably glass, comprising depositing a reflective metal, especially a silver, layer by a low pressure deposition process performed in a coating atmosphere that contains a gasous oxygen scavenger. The presence of the gasous oxygen scavenger alleviates oxidation of the silver layer by any oxygen gas present in the coating atmosphere. The gaseous oxygen scavenger may be a hydrocarbon and is preferably methane. The coating process is preferably sputtering.

Abstract: A process for the production of a low emissivity coating on a glass substrate comprising, in sequence, depositing a reflective metal layer, and reactively sputtering a metal oxide layer over the metal layer in the presence of an oxygen scavenger. The oxygen scavenger is preferably a hydrocarbon, in particular methane. The metal oxide layer may comprise tin oxide, zinc oxide, tungsten oxide and other metal oxides are also likely to be suitable.

Abstract: A high performance solar control glass comprises a glass substrate with a coating comprising a heat absorbing layer and a low emissivity layer of a metal oxide. Preferred heat absorbing layers absorb preferentially at wavelengths above 700 nm, and may be, for example, of non-stoichiometric or doped tungsten oxide, or of cobalt oxide, chromium oxide, iron oxide or vanadiam oxide. Preferred low emissivity layers are of semi-conductor metal oxide, for example doped tin oxide or doped indium oxide. Because of the nature of the layers, the coatings may be of neutral color and be suitable for deposition on-line on the glass ribbon, during the glass production process, by pyrolytic methods for example chemical vapor deposition.
