- logam Europium utama Efesus ing printing saka dhuwit kertas Euro. cathetan iki cemlorot abang ing lampu UV.
- Kang digunakake ing bolam lampu kurang energi.
- Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
- Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
