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.
