Effect of solvent on structure and optical properties of PZT nanoparticles prepared by sol–gel method, in infrared region
Source abstract
Abstract
Abstract Single-phase perovskite Pb(Zr 0.52 ,Ti 0.48 ) nanoparticles, PZT-NPs were prepared by the sol–gel method with two different solvents, 2-methoxyethanol, EGME, and poly ethylene glycol, PEG. X-ray diffraction (XRD) was used to study of the structure of the PZT-NPs. Fourier transform infrared spectroscopy (FTIR) was used to measure the infrared reflectivity spectrum in the range of 4000–280 cm −1 . Infrared active vibration modes of BO 6 octahedral ( ν 1 and ν 2 ) were observed for PZT-NPs below 600 cm −1 . The third vibration mode of Pb against the TiO 3 group, ν 3 , occurred below the experimentally accessible range. The Kramers–Kronig method (K–K) and classical dispersion theory were applied to analyze the data and calculation of the optical constants such as reflective index ( N ( ω ))and permittivity ( ɛ ( ω )). The results showed that the structure and optical properties of PZT-NPs were changed by different type of solvent.
