  • Publication number: 20100040892
    Abstract: A transparent conductive oxide (TCO) based film is formed on a substrate. The film may be formed by sputter-depositing, so as to include both a primary dopant (e.g., Al) and a co-dopant (e.g., Ag). The benefit of using the co-dopant in depositing the TCO inclusive film may be two-fold: (a) it may prevent or reduce self-compensation of the primary dopant by a more proper positioning of the Fermi level, and/or (b) it may promote declustering of the primary dopant, thereby freeing up space in the metal sublattice and permitting more primary dopant to create electrically active centers so as to improve conductivity of the film. Accordingly, the use of the co-dopant permits the primary dopant to be more effective in enhancing conductivity of the TCO inclusive film, without significantly sacrificing visible transmission characteristics. An example TCO in certain embodiments is ZnAlOx:Ag.

  • Patent number: 7648769
    Abstract: An absorbing layer of a low-E coating is designed to cause the coating to have a more bluish color at normal and/or certain off-axis viewing angles. In certain example embodiments, the metallic or substantially metallic absorbing layer (e.g., NiCr) is located in the middle section of the layer stack and has been found to unexpectedly provide desirable bluish glass side reflective color for the coated article at certain off-axis viewing angles (e.g., at a 45 degree off-axis viewing angle). In certain example embodiments, the absorbing layer is provided between first and second nitride inclusive or based layers in order to reduce or prevent oxidation thereof during heat treatment thereby permitting predictable coloration to be achieved following the heat treatment. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, vehicle windows, other types of windows, or in any other suitable application.

  • Patent number: 7462398
    Abstract: A coated article is provided that may be heat treated in certain example embodiments. A coating of the coated article includes a zinc oxide inclusive layer located over and contacting a contact layer that is in contact with an infrared (IR) reflecting layer of a material such as silver. It has been found that the use of such a zinc oxide inclusive layer results in improved thermal stability upon heat treatment, more neutral and/or desirable coloration, lower sheet resistance (Rs ), and/or lower emissivity.

  • Patent number: 7462397
    Abstract: A low-E coated article is provided, in certain example embodiments, with a layer including silicon nitride adjacent the glass substrate in order to improve chemical and/or mechanical durability of the coated article. In certain example embodiments, the coated article may be formed so as to have a fairly high visible transmission (TY or Tvis) to sheet resistance (Rs) ratio (i.e., a ratio Tvis/Rs) The higher this ratio, the better the coated article's combined functionality of providing for both good solar performance (e.g., ability to reflect and/or absorb IR radiation) and high visible transmission. Coated articles herein may be used in the context of windows or the like (e.g., laminated vehicle windshields).
