A method and apparatus for creating a flat optical structure is disclosed. The method includes etching at least one trench in a substrate, placing a dielectric material in at least one trench in the substrate and encapsulating the top of the substrate with a film.

A coated article includes a substrate, a first dielectric layer, a subcritical metallic layer having discontinuous metallic regions, a primer over the subcritical layer, and a second dielectric layer over the primer layer. The primer can be a nickel-chromium alloy. The primer can be a multilayer primer having a first layer of a nickel-chromium alloy and a second layer of titania. The subcritical layer can contain copper and silver.

A method of tinting or coloring glass. The following layers are deposited onto the glass: a first dielectric layer, a subcritical metallic layer; a primer layer; and a second dielectric layer. Alternatively, these layers may be deposited onto the glass: a first dielectric layer, a subcritical metallic layer; and a second dielectric layer. Alternatively, the invention is a coated article that includes a substrate, a first dielectric layer, an absorbing layer, and a second dielectric layer over the primer layer. The absorbing layer can be Inconel, titanium nitride, cobalt chrome (stellite), or nickel chrome material, and has a thickness in the range of 50 to 150 .

Provided is a refractive-index-matching thin film, which is an inorganic crystal thin film, wherein a matching layer including inorganic films having different refractive indices is formed on the surface of a substrate and, more particularly, to a refractive-index-matching thin film, which is configured such that a matching layer including one or more inorganic films having different refractive indices is formed on the surface of a substrate made of a polymer, ceramic, metal or combinations thereof, thus protecting the surface of flexible displays such as curved and bendable displays.

Coated articles for use in backsplash applications such as kitchen backsplashes, bathroom backsplashes, and bathroom floor/wall applications. The coated article includes a coating on a glass substrate, where the coating includes a plurality of dielectric layers and a plurality of metal-based layers and is configured so that the coated article has desirable glass side reflective coloration (e.g., bronze, blue, silver, and/or grey coloration) and is sufficiently opaque to hide adhesive used to adhere the coated article to walls/floors. The coating may be configured to realize thermal stability in order to have minimal or reduced glass side reflective color shift up heat treatment (e.g., thermal tempering).

A method for synthesizing nanoparticles includes aerosolizing a precursor solution in the presence of a flowing carrier gas to yield a reactant stream, the precursor solution comprising a volatile solvent and a nanoparticle precursor. The method further includes heating the reactant stream to a temperature above a boiling point of the volatile solvent to form a product stream comprising a plurality of nanoparticles, cooling the product stream, and passing the product stream through a collection liquid to collect the nanoparticles from the product stream.
