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.
