Evolution of Mn-Doped ZnO and Simonkolleite Phases from Thermally Oxidized Zinc Metal Sheets under MnCl₂ Mist

Abstract:

This study presents a novel work on the synthesis of Mn-doped ZnO microstructures via thermal oxidation of Zn metal sheet in the presence of MnCl₂ mist. Structural analysis via XRD shows the growth of ZnO particles for the sample oxidized in water vapor while simonkolleite and ZnO both formed for the samples oxidized with MnCl₂. Shifting of ZnO diffraction peaks suggests incorporation of impurity atom within the crystal lattice of the material. SEM images show layered formation of simonkolleite at the bottom and ZnO particles at the top of the substrate. At increasing MnCl₂ concentration, the growth of ZnO particles and simonkolleite phases were hampered which is attributed to the hindering of the oxidation process by the presence of Cl^- anion.
