I le 1901, na maua ai e Eugene Antole Demarcay se elemene fou mai le "samarium" ma faaigoa.Europium.Masalo e faaigoa lenei mea i le upu Europa.
Ole tele ole europium oxide o lo'o fa'aogaina mo pa'u fa'alelei.Eu3 + o loʻo faʻaaogaina e fai ma activator mo phosphors mumu, ma Eu2 + faʻaaogaina mo phosphors lanumoana.I le taimi nei, Y2O2S: Eu3 + o le paʻu felafolafoaʻi sili ona lelei mo le faʻamalamalamaga lelei, faʻamautu faʻamau, ma tau toe faʻaleleia.
E le gata i lea, o le faʻaleleia atili o tekinolosi e pei o le faʻaleleia atili o le malamalama ma le faʻatusatusaina o loʻo faʻaaogaina lautele.
I tausaga talu ai nei, o le europium oxide ua faʻaaogaina foi e avea o se faʻaoso faʻaosoina phosphor mo faiga faʻafomaʻi faʻafomaʻi X-ray fou.Europium oxidee mafai fo'i ona fa'aoga e gaosia ai tioata lanu
Ma o filiga fa'apitoa, fa'aaogaina i masini fa'aputu maneta, e mafai fo'i ona fa'aoga i mea fa'atonutonu, mea e fa'apipi'i ai mea, ma mea fa'atulagaina o mea fa'aatomika.
