Manufacturing Process

Gadolinium oxide nanoparticles can be manufactured using several methods. The commonly used one is the precipitation of the hydroxide via the reaction of gadolinium ions with hydroxide, which is followed by thermal dehydration to the oxide. The nanoparticles are coated with a protective material to prevent the formation of larger polycrystalline aggregates.

Applications

The key applications of gadolinium oxide nanoparticles are as follows:

  • Fluorescent materials, luminescence, and electroluminescent devices
  • Special optical glass and plasma display panels
  • In the electric industry
  • As additives, catalysts, and dopants
  • In cathode-ray tubes, ferroelectric memory, and field emission displays
  • High-resolution x-ray medical imaging
  • Neutron converter
  • Scintillators and sintering aids
  • Solid oxide fuel cell
  • UV detectors.
