Europium oxide (nke a makwaara dị ka europia) bụ ngwakọta kemịkalụ nwere usoro Eu2O3. Ọ bụ ụwa oxide na-adịghị ahụkebe na ihe siri ike na-acha ọcha nwere usoro kristal cubic. A na-eji Europium oxide mee ihe maka ịmepụta phosphor maka ojiji na tubes ray cathode na oriọna fluorescent, dị ka dopant na ngwaọrụ semiconductor, yana dị ka ihe na-eme ka ọ dị elu. A na-ejikwa ya na mmepụta nke ceramics na dị ka onye na-achọpụta ihe n'ime nchọpụta ndụ na nke kemịkal.

Ngwa

A na-eji Europium Oxide, nke a na-akpọkwa Europia, dị ka onye na-arụ ọrụ phosphor, ụcha cathode-ray tubes na ihe ngosi mmiri-kristal nke a na-eji na kọmputa na telivishọn na-eji Europium Oxide dị ka phosphor uhie; A maghị onye nọchiri anya ya. Europium oxide (Eu2O3) a na-ejikarị eme ihe dị ka phosphor na-acha uhie uhie na telivishọn na oriọna fluorescent, yana dị ka onye na-arụ ọrụ maka phosphor dabeere na Yttrium. A na-etinyekwa Europium Oxide na rọba ọpụrụiche maka ihe laser.
