METHOD AND APPARATUS FOR PRODUCING COLORED GLAZING Russian patent published in 2020 - IPC C03C17/00 C03C17/09 C03C17/245 C23C14/06 C23C14/34 

FIELD: glazing of buildings.

SUBSTANCE: in particular, disclosed is a method of depositing a coating on a glass substrate, characterized by a step of simultaneously spraying plasma simultaneously, in the same chamber of the vacuum deposition device: a first component of material consisting of oxide, nitride or oxynitride of the first element, and a second component consisting of a second element in form of metal, and a step, on which a hydride, a halide or an organic compound of a third element different from the first element is introduced into said plasma in order to obtain, at the output of said device, said substrate, coated with said coating. Said coating consists of metal nanoparticles of second element, distributed in inorganic matrix of said first and third elements, wherein said coating has a peak of plasmon absorption in the visible spectrum, and said peak can optionally be obtained through an additional heat treatment step. Also disclosed is an apparatus which enables to implement said method.

EFFECT: technical result is enabling creation of layers of different colors and in different proportions without intermediate losses of large amount of glass.
