The present disclosure is directed to optically transparent and IR reflecting films having a metal oxide based composite layer which can synergistically improve the optical properties, solar properties, and production speed of the whole composite.

A material includes one or more transparent substrates including two main surfaces, of which one of the surfaces of one of the substrates is coated with a functional coating capable of controlling solar radiation, the material including an absorbent layer for colorimetric adjustment of which the average absorption peak is centered between 500 and 555 nm and of which the full width at half maximum is less than 50 nm. The solar glazing has an improved aesthetic appearance without overly affecting thermal performance.

Certain example embodiments relate to coated articles with sequentially activated low-E coatings, and/or methods of making the same. In certain example embodiments, one or more infrared reflecting layers is/are activated via a non-equilibrium preconditioning activation that uses photons with specific frequencies/frequency ranges, followed by a more equilibrium thermal activation. The preconditioning activation aids in rearranging the silver atoms to energetically favorable positions, while helping to avoid their unwanted agglomeration. The more equilibrium thermal stage of activation aids in aligning the chemical potentials of the layers of the stack and in further densification of the preconditioned silver layer. Doing so, in turn, helps to reduce the likelihood of stresses building-up in the coating, the formation of point and dimensional defects, other unwanted efficiency-reducing phenomena, and/or the like. Advantageously, emissivity can be lowered to a value lower than that achievable using conventional thermal, flash, and laser scanning, approaches alone.

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 NiCrN.sub.x) and are each provided between first and second nitride layers (e.g., silicon nitride based layers) 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.

An insulating glass (IG) window unit including first and second glass substrates that are spaced apart from each other. At least one of the glass substrate has a triple silver low-emissivity (low-E) coating on one major side thereof, and a dielectric coating for improving angular stability on the other major side thereof.

Low-emissivity coatings that are highly reflective to infrared-radiation. The coating includes three infrared-reflection film regions, which may each include silver.

A material includes a transparent substrate deposited with a stack of thin layers on at least one of its surface for thermal insulation and aesthetic properties is disclosed. The stack of thin layers successively includes, starting from the substrate not more than two metallic functional layers based on silver F1, F2 and three dielectric coatings M1, M2, M3 including at least one dielectric layer such that each of the metallic functional layer is sandwiched between two dielectric coatings. The material including the stack of thin layers exhibits blue color in external reflection (R.sub.ext) and has less than 20% reflection internally and externally. Additionally, the material has a high selectivity while retaining a light transmission in the visible spectrum as less as 40%, and not higher than 50%.

The present disclosure is directed to optically transparent and IR reflecting films having a metal oxide based composite layer which can synergistically improve the optical properties, solar properties, and production speed of the whole composite.

The invention provides a glazing sheet and a low-emissivity coating on the glazing sheet. The low-emissivity coating comprises, in sequence moving outwardly from the glazing sheet, a layer comprising oxide film, nitride film, or oxynitride film, an infrared-reflective film, a nickel-aluminum blocker film, and an oxide film. Also provided are methods of depositing such a low-emissivity coating.

A hot plate includes a base plate having an underside. A coating has at least two metallic layers and at least two dielectric layers and is formed on the underside of the base plate in such a way that a reflectivity of the hot plate is lower than 15% in a wavelength range between 380 nm and 780 nm.
