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 zitsulo zadothi komanso ngati tracer mu kafukufuku wa zamoyo ndi mankhwala.
