Uses
Uses & Benefits
  • 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.
  
  • Uses of Scandium are limited to research purpose only. However, it has very low density and higher melting point.
  • Its compounds like scandium iodide is used in mercury vapor lamps to produce very bright white light.
