Overview

ZnO nanoparticles co-doped with Mn and Cu demonstrate ferromagnetism and variable optical properties based on doping levels, suggesting potential applications.

Key Points

  • The study aimed to investigate the structural and magnetic properties of Mn/Cu co-doped ZnO nanoparticles synthesized through a sol–gel method.
  • Synthesis of ZnO nanoparticles using varying concentrations of Mn and Cu via the sol–gel method.
  • Characterization of defect structures using photoluminescence and electron spin resonance spectroscopy.
  • Assessment of crystallite size and stresses using the Williamson–Hall method and X-ray diffraction.
  • Confirmed a hexagonal wurtzite structure in ZnO nanoparticles without secondary phases.
  • Observed ultraviolets and visible emissions in PL spectra, dependent on dopant concentration.
  • Detected ferromagnetism at room temperature in Mn/Cu co-doped nanoparticles.
