Mg doped ZnO nano particles were synthesized by chemical precipitation method and post processing was performed at two different annealing temperatures. The structural characterization was performed for all Mg doped ZnO samples using XRD and their results were compared with the results of undoped ZnO nano particles. As grown samples were the mixture of randomly orientated ZnO nano crystals along with Zn(OH)2 compounds and confirmed by XRD spectra. Annealing process was aided to decompose Zn(OH)2 compounds and observed pure ZnO compounds with preferred (100), (002) and (101) orientations. The peak intensity of preferred orientations was varied with respect to Mg concentrations and low for the samples of 6% M Mg (6MZO) annealed at 500°C. Highly intensive peak was noticed for 700°C annealed samples. Peak shifting towards low and high 2? values was noticed for 6MZO samples annealed at 500°C and 700°C respectively. Mg doping was influenced the crystallite size of ZnO nanoparticles and low value was observed with 6MZO sample. The lattice parameters of undoped and Mg doped ZnO nano particles were slightly changes with respect to the Mg concentrations and higher value was noticed with ?8 M% of Mg in ZnO. The dislocation density was also dependent on Mg concentrations as well as annealing temperatures and low values were noticed with low Mg concentrations for (002) oriented phase at annealed conditions. As grown samples were influenced by the mixture of tensile and compressive stress and high & low values in tensile stress were noticed with (002) orientate of 6MZO samples (9.18 x 10-2) and (100) orientation of 2MZO samples (8.76 x 10-4) respectively when annealed at 700°C.
