Description:

Gadolinium Oxide (Gd₂O₃) is a white, odorless, crystalline powder composed of gadolinium (Gd) and oxygen (O). It is an insoluble, thermally stable compound with high melting and boiling points.

  Key Properties:

  • High Refractive Index – Useful in optical coatings.
  • Magnetic Properties – Paramagnetic at room temperature.
  • Neutron Absorption – High neutron capture cross-section.
  • Luminescence – Used in phosphors and scintillators.

Applications:

Phosphors & Luminescent Materials

  • Used in X-ray scintillators (e.g., Gd₂O₂S:Eu³⁺ for medical imaging).
  • Acts as a host material for rare-earth-doped phosphors in LEDs and displays.

 Nuclear Applications

  • Neutron absorber in nuclear reactor control rods (due to high neutron capture ability).
  • Used in radiation shielding materials.

Electronics & Optics

  • Dielectric material in capacitors and semiconductors.
  • Used in optical coatings (e.g., anti-reflective, IR-reflective layers).

 Catalysts & Chemical Applications

  • Acts as a catalyst in hydrogenation and dehydrogenation reactions.
  • Used in oxygen sensors and fuel cells.

 Biomedical & Research Uses

  • Potential use in MRI contrast agents (as a precursor for gadolinium chelates).
  • Studied for nanoparticle-based drug delivery and bioimaging.
