Xyoo 1901, Eugene Antole Demarcay nrhiav tau ib lub ntsiab tshiab los ntawm "samarium" thiab muab nws lub npe.Europium.Qhov no tej zaum muaj npe tom qab lub sij hawm Europe.
Feem ntau ntawm cov europium oxide yog siv rau fluorescent hmoov.Eu3 + yog siv los ua tus activator rau liab phosphors, thiab Eu2 + yog siv rau xiav phosphors.Tam sim no, Y2O2S: Eu3 + yog qhov zoo tshaj plaws fluorescent hmoov rau luminescence efficiency, txheej stability, thiab rov qab nqi.
Tsis tas li ntawd, kev txhim kho hauv cov thev naus laus zis xws li kev txhim kho luminous efficiency thiab qhov sib txawv tau siv dav.
Nyob rau hauv xyoo tas los no, europium oxide kuj tau siv los ua lub zog emission phosphor rau X-ray kho mob kuaj kab mob tshiab.Europium oxidekuj tseem siv tau los tsim cov xim lo ntsiab muag
Thiab cov ntxaij lim dej kho qhov muag, siv hauv cov khoom siv sib nqus npuas, kuj tuaj yeem siv rau hauv cov ntaub ntawv tswj, cov ntaub thaiv npog, thiab cov khoom siv ntawm cov atomic reactors.
