Cycling stability of the photochromic effect in rare-earth oxyhydride thin films is of great importance for long-term applications such as smart windows. However, an increasingly …
We present in-situ studies of H loss from YHO films using ion beam analysis and its effect on the photochromic properties. The film evaporates loosely bound H under exposure to a …
We present a new analytical instrument for studying the optical properties of materials in different gaseous environments at room and controlled elevated temperatures. The system …
Oxygen‐containing yttrium hydride (YHO), primarily known for its photochromic properties, simultaneously shows a photoconductive response. Polycrystalline YHO thin films are …
Abstract Rare-Earth oxyhydrides (REH 3-2x O x) are characterized by photodarkening when illuminated by photons having an energy exceeding that of the band gap. We propose that …
We present equipment for sample synthesis, preparation and modification enabling in-situ studies employing medium energy ion beams at the ion implanter facility of the Tandem …
