Rare-earth oxyhydride REO x H 3–2 x thin films prepared by air-oxidation of reactively sputtered REH 2 dihydrides show a color-neutral, reversible photochromic effect at ambient conditions. The present work shows that the O/H anion ratio, as well as the choice of the cation, allow to largely tune th...
