Gadolinium as a metal or a salt absorbs neutrons and is, therefore, used sometimes for shielding in neutron radiography and in nuclear reactors. Like most of the rare earths, gadolinium forms trivalent ions with fluorescent properties, and salts of gadolinium(III) are used as phosphors in various applications.
Nanoparticles of gadolinium oxide is a potential contrast agent for magnetic resonance imaging (MRI). A dextran-coated preparation of 20–40 nm sized gadolinium oxide particles had a relaxivity of 4.8 s −1 mM −1 per gadolinium ion at 7.05 T (an unusually high field compared to the clinically used MRI scanners which mostly range from 0.5 to ...
Any rare-earth element can be used in a ReBCO; popular choices include yttrium , lanthanum , samarium (Sm123), [6] neodymium (Nd123 and Nd422), [7] gadolinium (Gd123) and europium (Eu123), [8] where the numbers among parenthesis indicate the molar ratio among rare-earth, barium and copper.
