Daim ntawv thov
tsawg ntiaj tebEuropium Chlorideyog siv los ua cov khoom siv raw ntawm phosphors rau 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. Europium Chloride kuj tseem siv rau hauv cov iav tshwj xeeb laser. Nyob rau hauv lub zog txuag hluav taws xob teeb pom kev zoo, Europium muab tsis tau tsuas yog qhov tsim nyog liab, tab sis kuj xiav. Ob peb lub lag luam xiav phosphors yog raws li Europium rau xim TV, lub computer cov ntxaij vab tshaus thiab fluorescent teeb. 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.
