Embodiment 1

[0064] This method can be used to stain glass bottles internally. In such cases, the surface controlled deposition of the ALD method is used to dope the additive on the inner surface of the bottle (or similar shape). In the method, a suitable glass tinting compound is deposited on the inside of the bottle. Then, by increasing the temperature, it diffuses into the structure of the inner surface. The result is a beautiful color and deep varnish-like color visible through glass surfaces. This can be used, for example, to prepare perfume bottles or to create an outstanding view of the product. Embodiment 1: Prepare Al by ALD method 2 o 3 / Er 2 o 3 doped glass blank

[0065] By depositing Al on the surface of porous glass blanks used to prepare optical fibers 2 o 3 / Er 2 o 3 layer, to investigate the functionality of the present invention, namely the use of the ALD method in doping porous glass materials.

[0066] Porous glass blanks were prepared using previously known...

Embodiment 2

[0078] After this, a silica cladding is formed around the ingot. Finally, the blank and cladding are sintered. The result is a transparent fiber blank that is stretched into fibers. Embodiment 2: Adopt MCVD and ALD method to prepare Al 2 o 3 / Er 2 o 3 doped glass blank

[0079] The use of the ALD / MCVD method of the present invention in doping glass materials was investigated using a combination of ALD and MCVD methods. In the study, the Al 2 o 3 / Er 2 o 3 The layers are deposited on the inner surface of the glass blank used to make the optical fiber.

[0080] Glass blanks were prepared using previously known MCVD methods. In the method, a glass tube consisting of synthetic quartz glass is fastened to a glass lathe in which the tube is rotated. Silicon tetrachloride SiCl 4 , phosphorus oxychloride POCl 3 , and silicon tetrafluoride SiF 4 stay inside the tube. The tube is heated with an oxyhydrogen flame from a quartz glass burner. In the hot spot created by the...

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 layeris 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.

Description

[0001] purpose of invention [0002] The present invention relates to methods of doping materials, doped materials and devices for doping materials. Background of the invention [0003] Many problems relate to the doping of materials, especially when the amount of dopant is significantly small compared to the amount of the matrix material. If the amount of the dopant is less than 1% of the amount of the matrix material, less than 1‰ or even less than 1 ppm, uniform doping by conventional methods cannot be achieved. On the other hand, even when the material to be doped is 1-10% or even 10% of the amount of the matrix material, problems with uniform doping can occur. The problem may then be that uniform doping takes an unreasonably long time. Non-uniform doping poses a problem because the properties of the material can vary greatly and uncontrolled between different parts of a component fabricated from the material. [0004] Doping can be used, for example, when producing mat...
