Abstract :
The undoped and Eu3+ doped Pb5(VO4)3OH rod bunches have been synthesized by a simple CHM method at 200 °C. The characterization of the rod bunches with XRD and XPS indicated that Eu3+ ions were incorporated into the Pb5(VO4)3OH lattice. The crystallite size of Pb5(VO4)3OH: Eu3+ rod bunches was smaller than that of pure Pb5(VO4)3OH rod bunches. The UV–visible spectrum showed that the optical band gap of the doped samples was larger than that of undoped samples. The magnetic properties of the undoped and doped Pb5(VO4)3OH rod bunches have been investigated at room temperature. The crystals exhibited room-temperature ferromagnetic behavior with the remanence magnetization (Mr) of 0.000903 and 0.00179 emu/g and coercivity (Hc) of 18.4 and 28.2 Oe for the Pb5(VO4)3OH and Pb5(VO4)3OH: Eu3+ rod bunches, respectively.
