Abstract
A description is given of a switching device ( ) comprising a transparent substrate ( ), a switching film ( ) comprising a hydride of scandium and magnesium, covered with a palladium layer ( ). By exchange of hydrogen, the switching film can be reversibly switched from a transparent state to a mirror-like state with zero transmission via an intermediate black absorbing state. The conversion between both states is reversible, and this phenomenon can be used, for example, in an optical switching element or sun roof.
