Abstract

The present invention relates to a method for producing a photochromic oxy-hydride material as well as a photochromic component. The method comprising the steps of: —first the formation on a substrate of a layer of an essentially oxygen free rare earth 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, said second step being performed in an environment having a water content defined by a water amount in air at sea level pressure with RH between >0% and 100% RH for temperatures between 0° C. and 40° C., preferably 25° Celsius.

Abstract

The present invention relates to a metal hydride device having a variable transparency, comprising a substrate, at least one layer including a photochromic yttrium hydride having a chosen band gap, and a capping layer at least partially positioned on the opposite side of the photochromic yttrium hydride layer from the substrate, said capping layer being essentially impermeable to hydrogen and oxygen.
