摘要:Terbium orthophosphate nanoparticles were synthesized using 1-hydroxy ethylidene-1,1-diphosphonic acid(HEDP) as a capping ligand under hydrothermal conditions at 80 degrees C. These HEDP-capped TbPO4 nanoparticles owned a hexagonal phase structure according to the powder X-ray diffraction(XRD) results and were spherical monodispersed particles with a diameter of about 10 nm confirmed by transimission electron microscope(TEM) images. Interestingly, the luminescent intensities of the HEDP-capped TbPO4 nanoparticles decreased obviously in the presence of Pb2+ ions and such a quenching behavior of luminescence was well fitted by the Stern-Volmer equation.
