Abstract: The energy saving glass comprises a substantially mutually parallel first surface and second surface, and the glass mass of the energy saving glass contains a solar radiation energy absorbing agent. The solar radiation energy absorbing agent is present in a layer of the glass mass which is close to the first surface, in which layer the concentration of the radiation energy absorbing agent substantially decreases when proceeding from the first surface deeper into the glass mass, such that the absorbing agent is present at the depth of at least 0.1 micrometres and not more than 100 micrometres as measured from the first surface of the glass. In the method, a layer of particulates is grown on the first surface of the glass, which particulates include at least one element or compound of the elements and diffuse and/or dissolve into the surface layer of the glass.

Abstract: Process for improving the chemical durability of glass by modifying at least one surface of a glass substrate. The modification process utilizes crystalline metal oxide particles with a mean aerodynamic particle diameter of less than 1000 nm, which are at least partially embedded on and into the glass surface. Apparatus for depositing crystalline metal oxide particles on glass surface.

Abstract: The invention relates to a method for doping and/or colouring glass. In the method a two- or three-dimensional layer is formed on the surface of the glass, and the layer is further allowed to diffuse and/or dissolve into the glass to change the transmission, absorption, reflection and/or scattering of the electromagnetic radiation of the glass. The layer of nanomaterial includes at least one component that causes the above-mentioned change and at least one component that lowers the melting point of the above-mentioned component causing the change.

Abstract: The invention relates to a method of modifying a surface of a glass product. The method comprises conveying particles to the surface of the glass, a material contained in the particles being at least partly dissolved and diffused in the glass. The method comprises a step of heating the surface of the glass. The invention further relates to an apparatus for modifying a surface of a hot glass product. The invention still further relates to glass products wherein the content of an element which provides the glass with a functionality decreases steplessly upon proceeding from the surface of the glass deeper into the glass.

Abstract: The present invention relates to an apparatus and a method for dyeing glass and, more particularly, an apparatus and a method, by which both surfaces of hot sheet-like glass may be dyed simultaneously and/or the surface containing tin residues of the sheet glass may be dyed to have a different colour than the surface without tin residues. The apparatus of the invention may be used for dyeing both sheet glass and utility glass, such as glass beakers.

Abstract: A method for modifying glassy surfaces including: producing nanoparticles; depositing the said nanoparticles on a surface; providing energy to the particles and/or surface so that the nanoparticles are at least partly diffused/dissolved into the glassy surface; and reducing the cohesive energy of the nanoparticles during the production of the nanoparticles or after the production of the nanoparticles.

Abstract: The invention relates to a method of selective doping of a material by a) radiating a predetermined pre-treated pattern/region into the material, b) treating the material for producing reactive groups in the pre-treated pattern/region, and c) doping the material by the atomic layer deposition method for producing a pattern/region doped with a dopant in the material. The invention further relates to a selectively doped material, a system for preparing a selectively doped material, and use of said method.

Abstract: The invention relates to a method for doping material, the method being characterized by depositing at least one dopant deposition layer or a part thereof on the surface of the material and/or on a surface of a part or parts thereof with the atom layer deposition (ALD) method, and further processing the material coated with a dopant in such a manner that the original structure of the dopant layer is changed to obtain new properties for the doped material. The material to be doped is preferably glass, ceramic, polymer, metal, or a composite material made thereof, and the further processing of the material coated with the dopant is a mechanical, chemical, radiation, or heat treatment, whereby the aim is to change the refraction index, absorbing power, electrical and/or heat conductivity, colour, or mechanical or chemical durability of the doped material.
