Synthesis of Ytterbium Monoxide under High Pressure
The rare earth elements except La, Ce, Pr, Gd, Tb, and Er are known to form stable divalent halides, but only Sm, Eu, and Yb appear to have a reasonable chance of forming divalent oxides stable in the solid State. The existence of EuO is well established and it has been made by a variety of methods. The mixed valence oxide of europium, Eu3 O4, is also known.
