摘要:
A coated article is provided with at least one infrared (IR) reflecting layer. The IR reflecting layer may be of silver or the like. In certain example embodiments, a titanium oxide layer is provided over the IR reflecting layer, and it has been found that this surprisingly results in an IR reflecting layer with a lower specific resistivity (SR) thereby permitting thermal properties of the coated article to be improved.
摘要:
Absorbing layers of a low-emissivity (low-E) coating are designed to cause the coating to have a reduced film side reflectance which is advantageous for aesthetic purposes. In certain embodiments, the absorbing layers are metallic or substantially metallic (e.g., NiCr or NiCrNx) and are positioned in order to reduce or prevent oxidation of the absorbing layers during optional heat treatment (e.g., thermal tempering, heat bending, and/or heat strengthening). Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, other types of windows, etc.
摘要:
A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrOx) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.
摘要:
Certain example embodiments of this invention relate to techniques for sputter-depositing a thin film(s) including two or more materials using targets such as rotating cylindrical sputtering targets, including a method and apparatus. Magnet bar assemblies in first and second adjacent sputtering targets are oriented differently. The different orientations of the magnet bar assemblies allows material from the second target to be sputtered onto the first target, or vice versa. The mixture of material on the first target, including sputtering material from both the first and second targets, is then sputtered onto a substrate to form a sputter-deposited thin film that includes a mixture of the sputtering materials from the targets.
摘要:
A coated article is provided which may be heat treated thermally tempered) in certain instances. In certain example embodiments, an interlayer of or including a metal oxide such as tin oxide is provided under an infrared (IR) reflecting layer so as to be located between respective layers comprising silicon nitride and zinc oxide. It has been found that the use of such a tin oxide inclusive interlayer results in significantly improved mechanical durability, thermal stability and/or haze characteristics.
摘要:
Certain example embodiments relate to techniques for depositing transparent conductive oxide (TCO) coatings using dual C-MAG sputtering apparatuses. Certain example embodiments provide a closed-loop system with the following process conditions. About 90% of the oxygen gas provided to the apparatus is provided via a top gas inlet. Pressure within the apparatus is increased to about 10−3 to 10−2 mbar, e.g., by providing an inert gas flow of at least about 600 sccm in certain example embodiments. Tube rotation is reduced to less than about 5 RPM. The power provided to the apparatus is adjusted in dependence on the presence or absence of oxygen partial pressure oscillations. TCOs such as, for example, ITO, ZnAlOx, SnSbOx, may be deposited according to the techniques of certain example embodiments.
摘要:
An absorbing layer of a low-E coating is designed to cause the coating to have a more neutral and/or green 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 from about 20-30 angstroms (Å) thick; this thickness has been found to unexpectedly provide less red and more neutral coloration 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 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.
摘要:
A plasma display panel (PDP) includes an EMI filter at a front portion thereof for blocking/shielding substantial amounts of electromagnetic waves. The filters has high visible transmission, and is capable of blocking/shielding electromagnetic waves. In certain example embodiments, a silver based coating of the EMI filter reduces damage from EMI radiation through highly conductive Ag layers, blocks significant amounts of NIR and IR radiation from outdoor sunlight to reduce PDP panel temperature, and enhances contrast ratio through reduced reflection, while maintaining high visible transmission. In certain example embodiments, at least one layer of or including silicon nitride may be Si-rich, and/or at least one layer including an oxide of Ni and/or Cr may be a suboxide, in order to improve heat treatability of the coated article.
摘要:
A mirror (e.g., first surface mirror) is provided with a layer of or including chromium nitride (CrNx). In certain example embodiments, the CrNx layer may be the primary reflective layer of the mirror. Surprisingly and unexpectedly, it has been found the addition of nitrogen to the chromium to form CrNx reduces pinhole formations in the resulting layer. In certain example embodiments, the more nitrogen which is introduced into the layer, the smaller the number and/or size of pinholes in the Cr inclusive layer. In certain example embodiments, it has also been found that the addition of nitrogen to Cr may improve durability.
摘要:
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).
