| Abstract: | In this study, the structural, microstructural, dielectric and piezoelectric properties of sol–gel processed rare earth doped Pb0.79La0.21TiO3 (PLT) samples with the composition Pb0.70La0.21Ln0.09TiO3 (Ln = Y, Gd, and Ce) (Ln-PLT), calcined for 4 h at 700 °C and sintered for 4 h at 1100 °C, were evaluated. Results of Raman spectroscopy and X-ray diffraction revealed that the Ln-PLT ceramics only showed the pseudo-cubic phase (P4mm), without any secondary phases, and that Ln atoms can occupy both Pb and Ti sites in the Pb0.70La0.21Ln0.09TiO3 matrix. As a result of substitution with Ln3+ ions, a reduction in the grain size of the Pb0.79La0.21TiO3 ceramic was revealed by Scanning Electron Microscopy analysis and that the average grain size in the ceramics was 845–1214 nm. The results of dielectric measurements indicated that the substitution by Ln3+ ions decreased the temperature of the dielectric constant maximum at the ferroelectric to paraelectric transition (FPT) and that the relaxation phenomenon in the frequency range 100–700 kHz was observed in Ln-PLT samples. Moreover, relatively high values of dielectric constant and low values of dielectric losses were obtained by substitution with Ln elements, and in all samples, the value of the dielectric constant’s maximum (εr max) to FPT revealed a particular behavior. The resonance phenomenon was appeared in the frequency-dependent permittivity, allowing the extraction of the electromechanical coupling factor, kp, which represented important values under doping with lanthanum and Ln elements.
