In recent years dilute magnetic semiconductors have paid much attention due to their complementary properties of semiconductors and ferromagnetic behavior. ZnO:Mn nano films doped with manganese different concentrations were deposited on glass substrates by the spin-coating method. The precursors for the synthesis ZnO:Mn are: Zinc acetate dehydrate, manganese acetate dehydrate, 2-mithoxyethanol and monoethanolamine as zinc and manganese source, solvent and stabilizer respectively. Characterization techniques of XRD and EDX measurements were done to investigate the effects of Mn doping concentration on the structural properties of ZnO:Mn nano films. The XRD patterns of all nano films show the crystallization behavior and are hexagonal wurtzite structure for different x, without existing other phases. The average crystallite size was also estimated by measuring fullwidth at half maxima of the intense diffraction peaks in all the compositions using Scherrer formula. Our results reveal that with high percent manganese not only the degree of crystalline decreases but also peak broadening occurs.
