Abstract

In this article, the structural, magnetic, and optical properties of CuO doped by cerium metal ions as a rare earth element synthesized by the hydrothermal method have been investigated. Various techniques such as X-ray diffraction (XRD) along with Rietveld refinement analysis, energy dispersive X-ray analysis (EDX), and field emission scanning electron microscopy (FESEM) have been used to investigate the crystalline and morphological properties. The results demonstrated that the samples crystallized in the form of polycrystalline and nanosheets with a monoclinic structure. Rietveld refinement of the sample showed sensible accord among the experimental data and standard CuO lattice constants. Also, the existing elements are evenly distributed on the surface of the sample and no impurity elements were observed in the material. By using UV-Vis absorption spectroscopy, the optical band gap of the sample was calculated at an acceptable value. To investigate the magnetic properties, a vibrating sample magnetometer (VSM) was carried out, which showed the weak ferromagnetic property of the Ce-doped sample.
