Praseodymium (Pr ion)-doped zinc oxide nanoparticles (Zn1−xPrxO, x = 0.00, 0.02, 0.05) were prepared by chemical co-precipitation method. The as-dried samples were annealed at 400 °C for 6 h duration in vacuum (10−2 mm of Hg). Crystallographic phase formation of each prepared sample is determined by matching the peak positions of the observed X-ray diffractograms with those of JCPDS file no. 76-0206...
Nanocrystalline sample of Ni2+ doped neodymium oxide (Nd1.90Ni0.10O3−δ, NNO) is synthesized by co-precipitation method. Analysis of X-ray diffraction (XRD) pattern by Rietveld refinement method confirms the desired phase of NNO and complete substitution of Ni2+ ions in the Nd2O3 lattice. Analyses of transmission electron microscopy (TEM) and Raman spectroscopy of NNO recorded at room temperature (RT) also...
