Europium oxide (eo hape e tsejoang e le europia) ke motsoako oa lik'hemik'hale o nang le foromo ea Eu2O3. Ke lefatše le sa tloaelehang la oxide le ntho e tšoeu e tiileng e nang le sebopeho sa kristale ea cubic. Europium oxide e sebelisoa e le lisebelisoa tsa ho etsa phosphors bakeng sa tšebeliso ea li-tubes tsa cathode ray le mabone a fluorescent, e le dopant lisebelisoa tsa semiconductor, hape e le ntho e thusang. E boetse e sebelisoa tlhahisong ea lirafshoa le joalo ka mohlala oa lipatlisiso tsa baeloji le lik'hemik'hale.
