Preferential Orientation of Photochromic Gadolinium Oxyhydride Films

Molecules, 2020
We report preferential orientation control in photochromic gadolinium oxyhydride (GdHO) thin films deposited by a two-step process. Gadolinium hydride (GdH2-x) films were grown by reactive magnetron sputtering, followed by oxidation in air.
