Abstract
A thin film device includes an active layer (4), wherein the active layer has optical properties that change by adding and removing hydrogen, and includes a Mg-transition metal layer, or rare earth based layer, the active layer being provided on one side with a protective layer (3) that is hydrogen, oxygen and water vapor permeable and liquid water impermeable, and has hydrophobic surface properties. The thin film can further include a Pd catalyst layer (5) disposed between the active layer (4) and the protective layer (3). The thin film device can be used in a switchable mirror wherein the optical properties of the mirror can be changed by adding/removing hydrogen to/from the active layer.
