Investigation on structural and functional properties of Nd doped BiFeO3 particles prepared by hydrothermal method
This study reports the effect of Nd-doping on structural, morphological and optical properties of BiFeO 3 synthesized by hydrothermal method. The X-ray diffraction’s results indicate that the samples possess single phase up to 12.5 % Nd doping at the Bi site, and all the samples were pure phase micr...

synthesized by hydrothermal method. The X-ray diffraction’s results indicate that the samples possess single phase up to 12.5 % Nd doping at the Bi site, and all the samples were pure phase microcrystal having a perovskite structure with a space group of R3c. Through the scanning electron microscope, we find that the particles are nearly spherical morphology and the size decreases with Nd doping. The study of Fourier transform infrared spectroscopy confirms the formation of perovskite structure of prepared BiFeO
