Synthesis, luminescent, and magnetic properties of LaVO4:Eu nanorods

The LaVO4:Eu nanorods were synthesized successfully by an ethylenediaminetetraacetic acid (EDTA)-mediated hydrothermal method. The resulting products were characterized using XRD, TEM, HRTEM, Fluorescence Spectrometer and SQUID magnetometer. It was found that Eu3+ entered into the LaVO4 crystalline host lattice and it replaced La3+. Consequently the unit cell parameters of LaVO4:Eu nanorods became smaller. Further studies indicated that the rare earth ions Eu3+ improved the properties of the LaVO4:Eu nanorods evidently. The Eu3+ ions doping in LaVO4 nanorods led to better luminescent properties and magnetic properties than that of pure LaVO4 nanorods.
