Daim ntawv thov:
Europium fluorideyog siv los ua phosphor activator rau cov xim cathode-duab tshav raj thiab cov kua siv lead ua kua siv nyob rau hauv lub computer saib thiab TVs siv Europium Oxide li liab phosphor. Ob peb lub lag luam xiav phosphors yog raws li Europium rau xim TV, lub computer cov ntxaij vab tshaus thiab fluorescent teeb. Europium fluorescence yog siv los soj ntsuam kev sib cuam tshuam ntawm biomolecular hauv cov tshuaj tshawb nrhiav tshuaj. Nws kuj tseem siv tau los tiv thaiv phosphors hauv eurobanknotes. Daim ntawv thov tsis ntev los no (2015) ntawm Europium yog nyob rau hauv quantum nco chips uas tuaj yeem ntseeg tau khaws cov ntaub ntawv rau hnub ntawm ib lub sijhawm; cov no tuaj yeem tso cai quantum cov ntaub ntawv khaws cia rau lub hard disk zoo li cov khoom siv thiab xa mus thoob lub tebchaws.
