Europium oxide (tseem hu ua europia) yog cov tshuaj sib xyaw nrog cov mis Eu2O3. Nws yog lub ntiaj teb tsis tshua muaj oxide thiab cov khoom siv dawb nrog cov qauv siv lead ua cubic. Europium oxide yog siv los ua cov khoom siv los ua phosphor rau siv hauv cathode ray hlab thiab cov teeb fluorescent, ua cov khoom siv hauv cov khoom siv semiconductor, thiab ua cov catalyst. Nws kuj yog siv nyob rau hauv zus tau tej cov ceramics thiab raws li ib tug tracer nyob rau hauv kev tshawb fawb lom thiab tshuaj lom neeg.

Daim ntawv thov

Europium Oxide, tseem hu ua Europia, yog siv los ua phosphor activator, xim cathode-ray raj thiab kua-crystal qhia siv nyob rau hauv lub computer saib thiab TVs siv Europium Oxide li liab phosphor; tsis muaj kev hloov pauv tau paub. Europium Oxide (ua 2o3) yog dav siv los ua cov phosphor liab hauv TV teeb thiab fluorescent teeb, thiab ua ib qho activator rau Yttrium-based phosphors. Europium Oxide kuj tseem siv rau hauv cov yas tshwj xeeb rau cov khoom siv laser.
