MULTIFUNCTIONAL USE OF LANTHANIDE DOPED VANADATE NANOPARTICLES
Optical properties of rare earth vanadates are characterized by a strong absorption of the [VO4]3- group, efficient energy transfer to lanthanide ions and their unique emissions coming from f-f electron transitions. These properties make them excellent laser materials and phosphors (the most well-known example being YVO4:Eu). When reduced to nanometer size these materials present some novel properties and functionalities.
This lecture presents methods of synthesis of different-size lanthanide-doped vanadate nanomaterials (AVO4, where A is rare earth or Bismuth ion), from ultra-small nanoparticles (2 to 4 nm in diameter) to micron size particles and thin films. Then their use in emerging applications is discussed. These applications include temperature and chemical sensing via luminescence, deep-tissue bio-imaging and photothermal therapy, structural characterization of nanofluids, and photocatalysis under visible light.
