Yttrium and lanthanum hydride films with switchable optical properties
Article Abstract:
Yttrium and lanthanum hydride thin films coated with a layer of palladium have switchable optical properties. Researchers stabilized thin films by coating them with palladium layers to induce metal-to-insulator transitions and allow hydrogen absorption. During continuous absorption of hydrogen, real-time transition from metallic to semiconducting behavior occurs along with alteration in optical characteristics. As the hydrogen concentrations changed, the films shifted froms transparent to mirrorlike. An electrochemical control mechanism may be easily devised.

Visualization of hydrogen migration in solids using switchable mirrors
Article Abstract:
Research indicates that hydrogen migration in solids is observable using switchable mirrors comprising of thin film. Combinations of hydrides yttrium and lanthanum or rare-earth metals are used to visualize optical linear hydrogen diffusion properties. Optical transmission profile scaling analysis using Boltzmann techniques are used.
