General description

Gadolinium(III) nitrate hexahydrate is a highly water-soluble crystalline oxidizing agent widely used as a precursor for the synthesis of specialty glasses, and ceramics and as a phosphor for light-emitting applications.

Application

Gadolinium(III) nitrate hexahydrate can be used:
  • As a precursor to synthesize Gadolinium oxide (Gd2O3) nanoparticles for various applications such as photocatalysis and biomedical imaging.
  • As a dopant to prepare ZnO nanoparticles with enhanced room temperature ferromagnetism.
  • To prepare Ceria (CeO2)-based ceramics doped electrolytes for intermediate temperature solid oxide fuel cells (IT-SOFCs) .
  • As a raw material for the synthesis of Eu3+-Activated KGd2F7 red-emitting nanoparticles for white light-emitting diode.
  • In addition,it is also reported to producegreen light emission of Er3+-activated single-phased GdAlO3 phosphors for lighting applications.

The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
