Investigation on the effect of Mn on structural and optical properties of ZnO nanoparticles

Zinc oxide and manganese added zinc oxide nanoparticles were synthesized by wet chemical technique. Highly stable pure and 0.5 weight percentage manganese doped Zinc Oxide nanoparticles have been prepared at room temperature. Characterization was carried out by FTIR, XRD, SEM, EDX and UV visible studies. The chemical composition of the products was characterized by FTIR spectroscopy. The detailed structural properties were examined using X-ray diffraction pattern which revealed that the synthesized nanoparticles are well crystalline and possessing wurtzite hexagonal phase. The SEM images of the samples clearly revealed the decrease in grain and porosity size with increasing concentration of Mn. The EDX results shown the presence of Zn, O and Mn.
