Europium Hlau, yog cov khoom tseem ceeb heev hauv kev tswj cov pas nrig rau nuclear reactors vim tias nws tuaj yeem nqus tau ntau dua neutrons dua li lwm cov khoom. Nws yog ib qho dopant hauv qee hom iav hauv lasers thiab lwm yam khoom siv optoelectronic. Europium kuj tseem siv rau hauv kev tsim cov iav fluorescent. Daim ntawv thov tsis ntev los no ntawm Europium yog nyob rau hauv quantum nco chips uas tuaj yeem ntseeg tau khaws cov ntaub ntawv rau hnub ntawm ib lub sijhawm.
