Erbium (Er) Nanoparticles- Properties, Applications

Nanoparticles research has garnered extensive interest as they find applications in myriad fields.

Erbium is Block F, Period 6 element. It is a rare earth element that does not oxidize as quickly as some other rare-earth metals. The morphology of Erbium nanoparticles is spherical, and they appear as a slivery powder.

Erbium nanoparticles are graded as highly flammable.

Researchers are assessing the possibilities of applying erbium nanocrystals as dopants in lanthanum fluoride, silicon and silicon matrix, glass and optical fibers, and also in phosphors, nanophosphors, and doped phosphorous nanoparticles.

Erbium oxide nanoparticles can be applied in the following products:

  • High-temperature corrosion-resistant coatings
  • Capacitors
  • Dopants for optical fiber and laser materials
  • Up-conversion material
  • Metal-oxide-semiconductor transistors
  • Tuned insulator for Josephson junctions
