FIG. 3.

The plots, recorded at RT, for the three samples, namely, A, vacuum annealed “B,” and air annealed sample “C.” The inset shows the plot of sample B exhibiting full saturation at .

FIG. 4.

Normalized XRD plots of the ZnO:Co (5%) samples A–C. The inset shows an enlarged view of the normalized XRD plots of the ZnO:Co (5%) samples A–C in a short range of values, from 33.6° to 35.2°.
