The present disclosure relates to products and methods for modifying the reflection of a light source in a fireplace and other products.

A material includes a transparent substrate coated with a stack of thin layers acting on infrared radiation including at least one functional layer. The stack includes a protective coating deposited above at least a part of the functional layer. The protective coating includes at least one lower protective layer based on titanium and zirconium, these two metals being in the metal, oxidized or nitrided form, and at least one upper protective layer of carbon, within which layer the carbon atoms are essentially in an sp.sup.2 hybridization state, located above the layer based on titanium and zirconium.

A glazing includes a transparent substrate coated with a stack of thin layers including at least one functional metal layer and at least two antireflective coatings, each antireflective coating including at least one dielectric layer, so that each functional metal layer is positioned between two antireflective coatings. The stack includes at least one silver-based functional metal layer including at least 95.0% by weight of silver, with respect to the weight of the functional layer, and from 0.5 to 3.5% by weight of zinc, with respect to the weight of zinc and silver in the functional layer.

A flexible displaying substrate includes: a first flexible film layer; a first barrier layer provided on a first surface of the first flexible film layer, and the first barrier layer is a constant-thickness film layer; a second barrier layer provided on one side of the first barrier layer away from the first flexible film layer; and a second flexible film layer is provided between the first barrier layer and the second barrier layer; wherein a surface of the second barrier layer closer to the first flexible film layer is provided with a slot, and a first orthographic projection of the second flexible film layer on the first flexible film layer and a second orthographic projection of the slot on the first flexible film layer at least partially overlap.

A material includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional metal layer. The stack includes a dielectric layer based on silicon and/or aluminum nitride located above a silver-based functional metal layer and an upper protective layer based on zirconium titanium oxide located above the dielectric layer based on silicon and/or aluminum nitride and exhibiting a ratio by weight of titanium to zirconium Ti/Zr of between 60/40 and 90/10.

Embodiments of a scratch-resistant and optically transparent material comprising silicon, aluminum, nitrogen, and optionally oxygen are disclosed. In one or more embodiments, the material exhibits an extinction coefficient (k) at a wavelength of 400 nm of less than about 1×10.sup.−3, and an average transmittance of about 80% or greater, over an optical wavelength regime in the range from about 380 nm to about 780 nm, as measured through the material having a thickness of about 0.4 micrometer. In one or more embodiments, the material comprises an intrinsic maximum hardness of about 12 GPa or greater as measured on a major surface of the material having a thickness of about 400 by a Berkovich Indenter Hardness Test along an indentation depth of about 100 nm or greater, low compressive stress and low roughness (Ra). Articles and devices incorporating the material are also disclosed.

A low-E (low emissivity) coating includes a multilayer overcoat designed for reducing fingerprints. The multilayer overcoat includes a layer comprising an oxide of zirconium (e.g., ZrO.sub.2) sandwiched between and contacting first and second layers of or including silicon nitride (e.g., Si.sub.3N.sub.4, SiO.sub.xN.sub.y, SiZrO.sub.xN.sub.y, or the like). The uppermost layer comprising silicon nitride modifies the surface energy of the layer comprising the oxide of zirconium so as to make the uppermost surface of the coating more hydrophilic, thereby reducing or minimizing interaction between zirconium oxide and finger oil to reduce fingerprints on the uppermost surface of the coating.

A laminate including a glass plate and a coating layer, wherein the coating layer includes one or more components selected from the group consisting of silicon nitride, titanium oxide, alumina, niobium oxide, zirconia, indium tin oxide, silicon oxide, magnesium fluoride, and calcium fluoride, wherein a ratio (dc/dg) of a thickness dc of the coating layer to a thickness dg of the glass plate is in a range of 0.05×10.sup.−3 to 1.2×10.sup.−3, and wherein a radius of curvature r1 of the laminate with negating of self-weight deflection is 10 m to 150 m.

An article is described herein that includes: a substrate having a glass, glass-ceramic or a ceramic composition and comprising a primary surface; and a protective film disposed on the primary surface. The protective film comprises a thickness of greater than 1.5 microns and a maximum hardness of greater than 15 GPa at a depth of 500 nanometers, as measured on the film disposed on the substrate. Further, the protective film comprises a metal oxynitride that is graded such that an oxygen concentration in the film varies by 1.3 or more atomic %. In addition, the substrate comprises an elastic modulus less than an elastic modulus of the film.

A method of producing a film of carbon nitride material, including the steps of providing a precursor of the carbon nitride material in a reacting vessel and a substrate substantially above the precursor of the carbon nitride material; heating the reacting vessel, the precursor of the carbon nitride material and the substrate at the first predetermined temperature; and quenching the reacting vessel to reach the second predetermined temperature; wherein the film of carbon nitride material is formed on a surface of the substrate during the quenching of the reacting vessel.
