Definitions
- DMD Dielectric-metal-dielectric
- a metal layer is sandwiched between two layers of dielectric material
- DMD Dielectric-metal-dielectric
- Berning et al., J __ Opt. Soc. Am. r H, 230 (1957) discloses a DMD coating having a silver layer and dielectric multilayer antireflection coatings on either side for use as band pass filters.
- Holland et al., Brit. J. Appl. Phys. , _&, 359 (1958) discloses a gold DMD coating which is transparent to visible light but infrared reflective. Additional publications related to DMD coatings are Plumat et al., CA 840,513 (1970) and Asahi Glass, GB 1,307,642 (1973) .
- Multilayer coatings are often used in architectural or automotive glazing applications, where high visible or solar light transmittance and infrared light reflectance are important, and in aircraft transparencies where high light transmittance and electrical conductivity are necessary. Further, it is very important that these coatings be environmentally stable, because of the harsh environments in which they are called to perform.
- the metal layers therein are usually very thin, often only 50-200 angstroms thick, and relatively fragile.
- Thin layers of certain metals such as silver are not particularly stable, especially at such extreme thinnesses, because of the metal's tendency to form sulfides or oxides (from reaction with chemicals in the environment) and to agglomerate.
- Antireflection layers may provide some protection by serving as corrosion barriers, but they themselves are also usually very thin, typically 200- 1000 angstroms thick, and cannot afford adequate protection, unless the multilayer coating is further protected by placing it in a laminate or other protective structure.
- this invention provides an article having a transparent, conductive, infra-red reflective coating with improved stability, comprising a substrate having on a surface thereof a transparent, conductive, infra-red reflective coating comprising a metallic layer sandwiched between two dielectric metal oxide layers, at least one of which is doped with a dopant metal selected from the group consisting of copper, gold, iron, nickel, cobalt, molybdenum, tungsten, platinum, vanadium, tantalum, titanium, chromium, magnesium, zirconium, nickel, aluminum, bismuth, lead, and alloys thereof.
- a dopant metal selected from the group consisting of copper, gold, iron, nickel, cobalt, molybdenum, tungsten, platinum, vanadium, tantalum, titanium, chromium, magnesium, zirconium, nickel, aluminum, bismuth, lead, and alloys thereof.
- an article having a transparent, conductive, infra-red reflective coating with improved stability comprising a substrate having on a surface thereof a transparent, conductive, infra-red reflective coating comprising a metallic layer and a dielectric metal oxide layer doped with a dopant metal as defined above.
- Fig. 3 is an XPS depth profile of a coating according to this invention.
- Fig. 4 is an XPS depth profile of another coating according to this invention.
- Fig. 5 compares the reflectance and transmission characteristics of coatings of this invention and a prior art coating, before environmental stability testing.
- Fig. 6 compares the reflectance and transmission characteristics of coatings of this invention and a prior art coating, after environmental stability testing.
- Fig. la depicts in cross-section an article 1 comprising a substrate 2 having deposited thereon a DMD coating 3 comprising dielectric layers 4a and 4b and metallic layer 5.
- At least one of dielectric layers is doped with a dopant as described in more detail hereinbelow, improving corrosion resistance of the metallic layer.
- Both dielectric layers can be doped, although where the substrate is a relatively impervious material such as glass, the inner dielectric layer 4b need not be doped.
- the substrate is a relatively pervious material such as a thin polymeric film, it is preferred that both dielectric layers be doped.
- Article 6 comprises a substrate 7 having deposited thereon a coating 8 comprising a dielectric layer 9 and metallic layer 10, the dielectric layer being doped as discussed above.
- this embodiment differs from the one shown in Fig. la in that there is no dielectric layer interposed between the substrate and the metallic layer.
- This embodiment may advantageously be used where the substrate is a relatively impervious material, so that there is a lesser threat of environmental attack from the substrate-facing side.
- Suitable dielectric materials for the dielectric layers include tin oxide, indium oxide, indium tin oxide, titanium oxide, zinc oxide and tantalum oxide. Preferred are tin, indium, or indium-tin oxide. While generally, as a matter of convenience, the dielectric layers are made of the same material, such is not a requirement.
- Suitable dopant metals include transition metals such as copper, gold, manganese, iron, nickel, cobalt, molybdenum, tungsten, platinum, vanadium, tantalum, titanium, chromium, magnesium, zirconium, nickel, and aluminum; group Illa-Va elements, including bismuth, indium, tin, and lead; and alloys thereof. Copper and gold are preferred.
- the metallic layer which is to be protected can be made of various metals. Silver, copper, and gold, which are often used in visible/solar transparent but infrared reflective, conductive coatings, are especially benefitted. Other metals which can be protected include platinum, palladium, nickel, and rhodium.
- the dopant metal forms an oxide with a heat of formation greater than that of the metal oxide corresponding to the metal of the metallic layer but less than that of metal oxide of the dielectric layer.
- the heats of formation preferably satisfy the following inequality: dielectric metal oxide > oxide of dopant metal
- the metallic layer is silver and the dielectric layer is tin oxide
- copper is a preferred dopant metal, as cupric oxide has a heat of formation of -167.5 kJ/mole, between that of silver oxide (-30.6 kJ/mole) and tin oxide (-580.7 kJ/mole) . While not wishing to be bound by theory, it is believed that in such an embodiment a corrosion protection effect is derived from the partial oxidation of the dopant metal in the dielectric layer.
- dopant metal such as copper
- doping levels of up to 28 atom % are possible, without seriously reducing the transmittance.
- dopants which form more transparent oxides than copper, such as aluminum considerably higher doping levels, up to 50 atom %, are tolerated without serious reduction in transmittance, as shown in Ritchie et al., U.S. Pat. 4,710,441 (1987) .
