Erbium Oxide


  • Used as colourant in glasses and porcelain enamel glazes. High purity Erbium Oxide is widely applied as dopant in making optical fibre and amplifier.
  • Used as gate dielectrics in semi conductor devices due to its high dielectric constant and large band gap.
  • Erbium Oxide nanoparticles on carbon nanotubes are used in biomedical applications due to its photoluminescent properties.
