APPLICATIONS OF GADOLINIUM
Gadolinium is utilized for both its high magnetic moment (7.94µB) and in phosphors and scintillator material.
When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. With its high magnetic moment, gadolinium can reduce relaxation times and thereby enhance signal intensity.
The extra stable half-full 4f electron shell with no low lying energy levels creates applications as an inert phosphor host. Gadolinium can therefore act as hosts for x-ray cassettes and in scintillator materials for computer tomography.
