| Kodi Europium(III) Oxide amagwiritsidwa ntchito chiyani? |
Europium(III) Oxide (Eu2O3) imagwiritsidwa ntchito kwambiri ngati phosphor yofiyira kapena yabuluu pama TV ndi nyali za fulorosenti, komanso ngati activator ya yttrium-based phosphors. Ndiwothandizira kupanga galasi la fulorosenti. Europium fluorescence imagwiritsidwa ntchito mu anti-counterfeiting phosphors mu ma banknotes a Euro.
