The objective of this work is to produce pure and Ni-doped Zn1-xNixO (where x = 0, 0.05, 01, or 0.15) nanoparticles using the sol-gel method. The samples were described using X-ray diffraction, UV-Vis spectroscopy, and vibrating sample magnetometer investigation. X-ray diffraction (XRD) was used to determine the hexagonal wurtzite structure of both pure and Ni-doped samples, showing no secondary phases or impurities. Pure and doped ZnO nanoparticles revealed a blue shift in the absorption edge in UV-Visible absorption edge. Moreover, magnetic characterization confirms room temperature ferromagnetism in Zn0.95Ni0.05O and Zn0.9Ni0.1O samples.

摘要

The objective of this work is to produce pure and Ni-doped Zn1-xNixO (where x = 0, 0.05, 01, or 0.15) nanoparticles using the sol-gel method. The samples were described using X-ray diffraction, UV-Vis spectroscopy, and vibrating sample magnetometer investigation. X-ray diffraction (XRD) was used to determine the hexagonal wurtzite structure of both pure and Ni-doped samples, showing no secondary phases or impurities. Pure and doped ZnO nanoparticles revealed a blue shift in the absorption edge in UV-Visible absorption edge. Moreover, magnetic characterization confirms room temperature ferromagnetism in Zn0.95Ni0.05O and Zn0.9Ni0.1O samples.
