Resultant peak dissection by match 3 in XRD of Mg doped ZnO nanoparticles

Abstract

Pure nanomaterials have limited applications, so to enhance the quality of the material, dopants play an important role in the application. It is important to find out whether the crystal structure of the dopant is rearranged or it preserves its crystal structure even after it is being doped in the pure material. Zinc Oxide has hexagonal structure and MgO has cubic structure. When Mg is doped in ZnO at various temperatures, MgO rearranges itself and it also has hexagonal structure in some cases and in other cases, it preserves or changes its crystal structure other than hexagonal structure represented as secondary peaks. Match 3 tool has been used for Mg doped ZnO at 500OC wherein MgO has rearranged itself into hexagonal structure and ZnO has rearranged itself into cubic structure. EDAX studies confirm that the synthesized material contains only Zn, O and Mg which confirm that the secondary peaks are due to structural interchange and not due to any other impurities.
