| Hei aha te Europium(III) Oxide? |
Ko te Europium(III) Oxide (Eu2O3) e whakamahia nuitia ana hei ūkuikui whero, kahurangi ranei i roto i nga pouaka whakaata me nga rama rama, me te whakakorikori mo nga phosphors-a-yttrium. He kaihoko ano mo te hanga karaehe kareoro. Ko te Europium fluorescence e whakamahia ana i roto i nga phosphors anti-counterfeiting i roto i nga moni putea Euro. He nui te kaha o te Europium oxide hei rauemi whakaahua mo te whakahekenga whakaahua o nga parahanga pararopi.
