General description

Europium(III) nitrate pentahydrate is a white crystalline solid with luminescent properties. It is widely used as a precursor to fabricate nanomaterials and perovskite solar cells.

Application

Europium(III) nitrate pentahydrate can be used:
  • As a precursor to synthesize Y2O3:Eu3+ thin-film phosphors by sol-gel method for display applications.
  • As a dopant to prepare crystalline nanophosphors. These are suitable for bioimaging as they are hydrophilic in nature and white light-emitting diodes.
  • To fabricate dye-sensitized solar cells with enhanced light-harvesting efficiency.
  • As a dopant to prepare various metal oxide nanoparticles, for example, ZnO nanoparticles for photocatalytic application.
