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.
