| Chii chinonzi Europium(III) Oxide inoshandiswa? |
Europium(III) Oxide (Eu2O3) inoshandiswa zvakanyanya se phosphor tsvuku kana yebhuruu mumaseti eterevhizheni uye marambi efluorescent, uye se activator yeyttrium-based phosphors. Iyo zvakare mumiriri wekugadzira girazi refluorescent. Europium fluorescence inoshandiswa mu-anti-counterfeiting phosphors muEuro banknotes.Europium oxide ine simba guru semafotoactive zvinhu zve photocatalytic degradation ye organic pollutants.
