Gadolinium Luminescent Materials Obtained by Spray Pyrolysis, Co-Precipitation, and Non-Hydrolytic Sol-Gel Route: Structure and Optical Properties
Résumé :
Terbium (Tb) is a soft, malleable, silvery white rare earth metal. It is
primarily used in solid state devices, crystal stabilizer in fuel cells,
sensor devices and in sonar systems. 70 % of the world supply of Tb is
used in the television sets as green phosphors. The other practical
applications of Tb include as an additive in magneto-restrictive alloys
which changes length when subjected to a magnetic field. Gadolinium
(Gd) is a metal ion with paramagnetic properties. This characteristic of
Gd makes it particularly suitable for use as a contrast agent in magnetic
resonance imaging (MRI). Gadolinium imaging has become an
essential tool in the non-invasive evaluation of cardiovascular
pathologies. Its current uses range from ischemia detection, viability
assessment, cardiomyopathy study and non-invasive angiography, and
its diagnostic and prognostic value has been demonstrated in multiple
studies. This book discusses the chemical properties of both Tb and
Gd, as well as the sources in which they can be found, and how they
can be used. (Imprint: Nova)
