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.
