- Abstract
In the present work, we have synthesized Zn1-xCoxO(x = 0.0 ≤ x ≤ 0.1) nanoparticles by an auto-combustion method using C2H5NO2 (glycine) as a fuel. The prepared nanoparticles were characterized by using X-ray diffraction, transmission electron microscopy, Photo-luminescence (PL) and magnetization measurements. XRD and TEM results demonstrated that Co-doped ZnO have a single phase nature with wurtzite structure and Co2+ ions were successfully incorporated into the lattice position of Zn2+ ions in ZnO matrix. PL spectra show two emission bands in visible region. Magnetic studies showed that Co-doped ZnO nanoparticles exhibit room temperature ferromagnetism.
