Europium oxide (yemwenso amadziwika kuti europia) ndi mankhwala omwe ali ndi formula Eu2O3. Ndiwosowa padziko lapansi okusayidi ndi zoyera zolimba zokhala ndi mawonekedwe a cubic crystal. Europium oxide imagwiritsidwa ntchito ngati chinthu chopangira phosphors kuti igwiritsidwe ntchito mu machubu a cathode ray ndi nyali za fulorosenti, ngati dopant mu zida za semiconductor, komanso ngati chothandizira. Amagwiritsidwanso ntchito popanga zoumba komanso ngati tracer mu kafukufuku wachilengedwe ndi mankhwala.

Kugwiritsa ntchito

Europium Oxide, yomwe imatchedwanso Europia, imagwiritsidwa ntchito ngati phosphor activator, machubu a cathode-ray ndi mawonedwe amadzimadzi omwe amagwiritsidwa ntchito pamakompyuta ndi ma TV amagwiritsa ntchito Europium Oxide ngati phosphor yofiira; palibe choloweza mmalo chomwe chimadziwika. Europium oxide (Eu2O3) amagwiritsidwa ntchito kwambiri ngati phosphor yofiira pamawayilesi a kanema ndi nyali za fulorosenti, komanso ngati activator ya phosphors yochokera ku Yttrium. Europium oxide imagwiritsidwanso ntchito mu pulasitiki yapadera pazinthu za laser.
