“…However, the 5% doping shows peaks corresponding to Mn3O4 phase. In synthesizing Mn-doped ZnO nanoparticles (1, 2 and 3%) by coprecipitation method, Yuwita et al [10] uses dehydrate zinc acetate and manganese powders and HCl and NH4OH solvents as precursors. The solution, stirred for 4h at 80 ºC was heated at 100 ºC for 24 hrs.…”

There is a substantial amount of literature dealing with many aspects of synthesis and characterization of pure and doped binary compounds including Mn-doped ZnO which has been widely studied due to its superb properties as a dilute magnetic semiconductor (DMS). Aspects concerning doping limits for these compounds is an important stage in the search for new materials. Samples of Zn1-xMnxO nanocrystal were synthesized at temperatures of 180 °C and 200 °C using wet or liquid phase synthesis method. Dopant concentrations x=0.5, 1, 1.5, 2, 2.5, 5, 10, 20, 30, 40 and 50 per cent were studied. Powder x-ray diffraction (PXRD) patterns of the samples were analyzed with a view to determining the onset of secondary phases and hence the solubility limit of the dopant. The solubility limit for Mn in ZnO samples synthesized at temperature of 200 °C is realized at x <20%. For samples synthesized at temperature of 180 °C, the solubility limit is x <0.5%.
