The xerogel was calcinated at temperature of 700 °C. The structure of the prepared powders is characterized using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The XRD results show that the PZT-NPs are formed in perovskite structure with tetragonal phase. In addition, a small shift was detected in XRD patterns of doped PZT-NPs. Also, to have a better understanding of the optical properties of the pure and doped PZT-NPs, the obtained FTIR spectra were analyzed. M3 ER -
