ʻO ka Europium oxide (ʻike pū ʻia ʻo europia) he hui kemika me ke ʻano Eu2O3. ʻO ia ka ʻokikene honua kakaʻikahi a me kahi mea paʻa paʻa keʻokeʻo me kahi ʻano aniani cubic. Hoʻohana ʻia ka Europium oxide ma ke ʻano he mea hana no ka hana ʻana i nā phosphors no ka hoʻohana ʻana i nā paipu ray cathode a me nā kukui fluorescent, ma ke ʻano he dopant i nā mea semiconductor, a ma ke ʻano he catalyst. Hoʻohana ʻia ia i ka hana ʻana i nā seramika a ma ke ʻano he tracer i ka noiʻi biological a me kemika.

Hoʻohana ʻia ʻo Europium Oxide, i kapa ʻia ʻo Europia, ma ke ʻano he phosphor activator, color cathode-ray tubes a me ka wai-crystal displays i hoʻohana ʻia i nā monitor computer a me nā televise e hoʻohana i ka Europium Oxide ma ke ʻano he phosphor ʻulaʻula; ʻaʻohe mea i ʻike ʻia. Europium Oxide (Eu2O3) ua hoʻohana nui ʻia ma ke ʻano he phosphor ʻulaʻula ma nā keʻena televise a me nā kukui fluorescent, a ma ke ʻano he mea hoʻoikaika no nā phosphors-based Yttrium. Hoʻohana ʻia ʻo Europium Oxide i loko o ka plastic kūikawā no ka mea laser.
