Abstract
Mn doped ZnO (Zn: Mn) nanopowder is successfully synthesized using the solvothermal route with concentration (X = 2%–8%) and annealing at 450 °C. The resulting material is investigated using various techniques. XRD studies confirm the structure of hexagonal wurtzite and good crystallinity in nature. From FESEM analysis confirms the formation of nanoparticles and allows for evaluation of the particle size of the sample. UV–Vis studies are used to determine absorbance wavelength and energy bandgap values. PL and EPR spectra confirm of the existence of zinc vacancy defects and g values are calculated. Interestingly, magnetic measurements revealed that the low concentration exhibited superparamagnetic behavior, while the high concentration showed a soft ferromagnetic structure using VSM.
