“…PZT ceramics formed by this method is heterogeneous in composition, containing compositional fluctuation and fixed morphology [4,5]. Thus, to prepare PZT powders with homogeneous compositions and fine structure, and different morphology many solution techniques have been investigated, such as hydrothermal synthesis [6,7], sol-gel combustion [8][9][10][11], sol-gel co-precipitation [12], electrohydrodynamic atomization [13,14], ultrasonic spray combustion synthesis (USCS) [15] and sol-gel [16][17][18]. Amongst all these methods sol-gel has been found to be more commonly used synthesis route to prepare materials of high chemical reactivity [19].…”

Nanopowder samples of lead zirconate titanate (Pb1.1Zr0.52Ti0.48O3 or PZT) were prepared by the sol‐gel method with controlled pH values. The samples were characterized using FTIR spectroscopy, XRD, FE‐SEM, and TEM techniques. Most of the peaks in the XRD pattern were related to the coexistence of tetragonal‐rhombohedral phases and confirmed the formation of PZT with a perovskite structure. Also, the crystallite size of PZT nanopowders was in a range of 17‐28 nm. FTIR spectroscopy revealed a longitudinal optical (LO) and transverse optical (TO) phonon modes corresponding to the stretching vibration of Ti‐O and Zr‐O bonds. The influence of pH values on the LO and TO phonon modes, LO‐TO splitting, refractive index n(ω), extinction coefficient k(ω), and the real ɛ1(ω) and imaginary ɛ2(ω) parts of dielectric function was discussed. These properties were investigated in the mid‐infrared region (450‐750 cm−1). The energy loss function Im[−1/(ɛ)] of PZT nanopowders was obtained by Kramers‐Kronig dispersion relations. The TO phonon frequency decreases with increasing crystallite size of the PZT samples. This effect does not happen at pH 8 to pH 9. As the crystallite size increased from 17.26 nm (at pH 5) to 27.25 nm (at pH 7), the LO‐TO splitting increased as well. This result showed that the optimum pH for absorption of IR radiation and optical application was at pH 7.

“…Several methods have been investigated to prepare PZT nanoparticles (PZT-NPs), such as: hydrothermal [3,13], sol-gel combustion [14][15][16], co-precipitation [17], electrohydro-dynamic atomization [18,19] and sol-gel [2, 20,21]. The sol-gel method is a process used in preparing materials for example nanoparticles, films, and bulk forms [21][22][23].…”

The aim of this work was to synthesize lead zirconate titanate (PZT) nanopowder using a modified solgel processing method. PZT obtained by a sol-gel route using acetic acid had compositions in the morphotropic phase boundary (Ti/Zr, 53/47 and 45/55). All samples were annealed in air at 800°C and sintered at temperature above 1,000°C. Structure and morphology of the samples were determined and characterized by X-ray diffraction, transmission electron microscopy, Raman spectroscopy, dilation, densification and pyroelectric response. Results of X-ray diffraction on samples PZT showed a phase, but not a pyrochlore one, which we determined to be the best pyroelectric response. The samples presented high densification and had appropriate characteristics when used as pyroelectric sensors. Ceramics with a composition of 53/47 had the best pyroelectric response. An average particle size of 20 nm was measured using TEM.
