Abstract:
A method for producing a glass or glass ceramic composite material is provided. The method includes: providing a glass or glass ceramic substrate with a coefficient of thermal expansion of α≦5*10−6 K−1; applying a sol-gel layer onto the substrate; adding particles to the sol-gel layer; patterning the sol-gel layer; thermally curing the sol-gel layer; and applying at least one further layer using a deposition process.
Abstract:
The present disclosure relates to a method for deposition of an anti-reflection layer, in which glass particles are embedded in a titanium oxide containing matrix that is produced by a sol-gel method.
Abstract:
The invention relates to a method for producing stable suspensions of finely dispersed colloidal crystalline titanium dioxide particles, comprising the hydro-thermal treatment of aqueous molecularly disperse sol-gel solutions prepared from amorphous water-soluble precursor powders. The suspensions thus obtained can be used, inter alia, for the production of thin transparent crystalline layers.
Abstract:
A semi-transparent coating material for coating glass or glass ceramics includes at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.
Abstract:
An etching method for selective introduction of structures into surfaces of different substrates, such as glass or glass ceramic substrates, is provided. The method provides for surface structuring using an etch mask. The etchmask allows for the production of very fine structures on the substrate surfaces using liquid etching media. In this method the etch mask is produced on the substrate.
Abstract:
The solar cell has a pigmented dielectric reflector, which includes two dielectric layers with different refractive indices and pigments embedded in the layers, so that the solar cell has good light-trapping properties and high efficiency with a small reflector layer thickness. The material systems suitable for producing the pigmented dielectric reflector are also part of the invention.
Abstract:
A composite material for LED's is provided. The composite material has a coating comprising scattering particles with an index of refraction greater than 1.6.
Abstract:
A composite material designed as a substrate glass for LED's is provided. The composite material includes a structured coating made of a hybrid polymer matrix that contains nanoparticles made of an oxide.
Abstract:
The invention relates to a method for producing a glass or glass-ceramic article, comprising a decorative layer and a sealing layer. The two layers are produced by means of a sol-gel process and contain, in addition, at least fillers and inorganic pigments, wherein it is possible for the pigmentation of the decorative layer and the sealing layer to be the same or else different. In order to achieve a good adhesive strength and impermeability of the decorative coating, certain composition rules in regard to the quantity and kind of inorganic pigments used must be observed and, surprisingly, are different for the sealing layer according to the invention than for the decorative layer. The invention relates, furthermore, to a glass or glass-ceramic article with decorative coatings, produced particularly according to the method of the invention, said article being suitable especially for use as glass-ceramic cooktops.
Abstract:
A display device is provided that is a transparent, colored glass-ceramic with a display face on the front, an illumination face on the back, and at least one light-emitting element being disposed in the region of the illumination face. The display device further includes a color compensation filter in the form of a color layer introduced directly or indirectly on the glass ceramics.
