Synthesis and Characterization of Nano-Dimensional Nickelous Oxide (NiO) Semiconductor

Abstract

In this work, single crystalline, defect free metal oxide (NiO) nanoparticle with diameter ~40nm was synthesized by only two steps soft chemical synthesis route. The crystalline nature of the sample was studied by X-Ray Diffraction method. TEM and HRTEM analysis was done to examine the morphology of the as prepared sample. The SAED pattern indicates the same crystal planes obtained from XRD study. The optical absorption characteristics were studied by UV-Vis Spectrophotometer and result shows the strong absorption peak at 3.75eV and nearly transparent nature of the nanoparticle at visible region. The photoluminescence properties were characterized by Fluorescence Spectrophotometer where the emission peaks was found at 3.62eV.
