Uses & Benefits
- Terbium salts are used in optical devices like laser devices.
-
Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
- Europium metals main uses is in the printing of euro banknotes. These notes glow red under UV light.
-
It is used in low energy light bulbs.
