ʻO Europium Metal, he mea waiwai loa ia i nā koʻokoʻo mana no nā reactors nuklea no ka mea hiki iā ia ke komo i nā neutrons ma mua o nā mea ʻē aʻe.He dopant ia i kekahi mau ʻano aniani i nā lasers a me nā mea hana optoelectronic ʻē aʻe.Hoʻohana ʻia ʻo Europium i ka hana ʻana i ke aniani fluorescent.ʻO kahi noi hou (2015) o Europium i loko o nā pahu hoʻomanaʻo quantum hiki ke mālama pono i ka ʻike no nā lā i ka manawa;hiki i kēia mau mea ke ʻae i ka ʻikepili koʻikoʻi e mālama ʻia i kahi mea like me ka diski paʻakikī a hoʻouna ʻia a puni ka ʻāina.
