Nan. Res. VL - 3 IS - 1 SE - Research Articles DO - 10.21467/anr.3.1.28-39 UR - https://journals.aijr.org/index.php/anr/article/view/2806 SP - 28-39 AB - <p>Powder samples of Zn<sub>1-x</sub>Mn<sub>x</sub>O nanocrystal were synthesized at a temperature of 200 °C using solid phase method. Dopant concentrations of 0.005 ≤ x ≤ 0.5 were studied. Powder x-ray diffraction (PXRD) patterns of the samples were analyzed with a view of determining the onset of secondary phases, hence the solubility limit of the dopant. The solubility limit for Mn in ZnO samples synthesized at 200 °C is realized at x &lt; 0.3. With a regular pattern in increment of the Mn concentration, there were variations observed in the trend of the relative intensity, 2θ position and d-spacing indicating uneven addition of Mn (thus Mn<sup>2+</sup>, Mn<sup>3+</sup> or Mn<sup>4+</sup>).</p> ER -
