Characterization of Lead Lanthanum Zirconate Titanate Ceramics Co-Doped with Lanthanide Ions

Abstract:

The aim of this work was to obtain Pb_0.92(La_0.08)(Zr_0.65Ti_0.35)_0.98O₃ materials co-doped with two different lanthanide ions (Ln³⁺) and characterization how they influence on the physical properties of prepared 8/65/35 PLZT: Ln³⁺ ceramics. As a co-dopant, praseodymium (Pr³⁺) and neodymium (Nd³⁺) ions were used at the concentration of 0.0 and 0.5 wt.% respectively. The ceramic powders of 8/65/35 PLZT, PLZT:Pr³⁺ as well PLZT:Nd³⁺ were synthesized by conventional ceramic route, from high purity raw oxide materials (>99,9%). All compositions of the ceramic samples were sintered via single time process at T_s=1200°C/3h, by the hot uniaxial pressing method. Performed measurements have shown dependence of used dopant on structure, microstructure, and dielectric as well optical properties of the fabricated 8/65/35 PLZT: Ln³⁺ materials.
