    Abstract: Optical switching device comprising a substrate on which a magnesium transition metal layer such as a magnesium nickel metal layer is provided. At supplying of hydrogen the magnesium transition metal layer is, starting from the substrate, converted to a magnesium transition metal hydride layer. This has optical properties different from the magnesium transition metal layer. The change in optical properties viewed from the transparent substrate side can change from reflective to transparent wherein a black phase is in between. To obtain and maintain this black phase is relatively critical. However, there are many applications in which such a black phase could be very useful. In order to be able to obtain a stable black phase according to the invention it is proposed to have a relatively thin magnesium metal layer for example of 50 nm at the maximum and to provide an auxiliary layer on top of the magnesium transition metal layer.
