Mu 1901, Eugene Antole Demarcay adapeza chinthu chatsopano kuchokera ku "samarium" ndipo adachitcha.Europium. Izi mwina zimatchedwa dzina la Europe.
Ambiri a europium oxide amagwiritsidwa ntchito popanga fulorosenti. Eu3 + imagwiritsidwa ntchito ngati choyambitsa ma phosphors ofiira, ndipo Eu2 + imagwiritsidwa ntchito ngati phosphors ya buluu. Pakalipano, Y2O2S: Eu3 + ndiye ufa wabwino kwambiri wa fulorosenti wa luminescence, kukhazikika kwa zokutira, ndi mtengo wochira.
Kuphatikiza apo, kuwongolera kwaukadaulo monga kuwongolera magwiridwe antchito ndi kusiyanitsa kumagwiritsidwa ntchito kwambiri.
M'zaka zaposachedwa, europium oxide yagwiritsidwanso ntchito ngati phosphor yotsitsimutsa yamagetsi atsopano a X-ray.Europium oxideangagwiritsidwenso ntchito kupanga magalasi achikuda
Ndipo zosefera zowoneka bwino, zomwe zimagwiritsidwa ntchito pazida zosungiramo kuwira kwa maginito, zitha kugwiritsidwanso ntchito poyang'anira zida, zotchingira, ndi zida zamapangidwe a ma atomiki.
