Abstract
Method for producing a photochromic material and a component including the photochromic material, where the method comprises the steps of:—first the formation on a substrate of a layer of an essentially oxygen free metal hydride with a predetermined thickness using a physical vapor deposition process; and—second exposing the metal hydride layer to oxygen where the oxygen reacts with the metal hydride, resulting in a material with photochromic properties.
Claims21
A method for producing a photochromic material, the method comprising:
- forming, on a substrate a layer of an essentially oxygen free metal hydride with a predetermined thickness using a physical vapor deposition process;
- and
- exposing the metal hydride layer to oxygen, where the oxygen reacts with the metal hydride, resulting in a material with photochromic properties.
A photochromic component comprising:
- a first, transparent substrate;
- and
- a layer constituted by at least a metal oxide and at least one of a metal oxy-hydride and a metal hydroxide.
