Undoped and Zr-doped with varying concentrations (1%, 3%, and 5%) ZnO nanoparticles were successfully synthesized through auto combustion route. We have studied the structural and optical properties of synthesized samples by using X-ray diffraction (XRD), field scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, UV–Vis spectroscopy and Raman spectroscopy. The XRD patterns for undoped and doped ZnO, reflect the various planes of wurtzite ZnO, indicating a single phase native of the samples. The peaks shifted to the low angle side followed by moderate changes of Zr assimilation in ZnO, these trends reveal the gradual expansion in crystal lattices, and this may be due to the additional interstitial incorporation of Zr. The optical absorption spectra for synthesizing samples show the absorption in the visible region. The spectra showed a red shift in the near band edge …
