Summary: In this study, a semi-solution method was used to enhance the dielectric and ferroelectric properties of acceptor-donor co-doped BaTiO3 ceramics, achieving higher peak dielectric constant and maximum polarization with less apparent aging phenomena. Microscopic analysis revealed that the property enhancement was attributed to the control of compositional homogeneity and oxygen vacancies.

Summary: The electrical transport properties of undoped and 2% yttrium-doped polycrystalline BaTiO3 at high temperature and pressure were studied using a diamond-anvil cell. It was found that doping with 2% Y ions led to a decrease in the Curie transition temperature. Increasing pressure significantly reduced the Curie temperature, with the decreasing rate gradually decreasing as well.

Summary: The tetragonality and phase-transition temperature of BaTiO3 ceramics doped with rare-earth Sm decreased with increasing doping content. Colossal dielectric constant and dielectric relaxations were observed, attributed to the inhomogeneous structure and interface-polarization effect. The multi-relaxation phenomenon depended on doping content and reflected the complex inhomogeneity of the samples, with relaxation processes closely related to the electrical resistances of the grain and activation energies dependent on the crystal structures.

Summary: Lead-free BiFeO3-BaTiO3 ceramics with excellent electrical properties were prepared by chemical doping and quenching process. The influences of Li/Al substitution on the structure, defects, and electrical properties of BF-BT-xLiAl were studied. The increase in the DC conductivity activation energy indicates a decrease in the oxygen vacancy concentration after Li/Al substitution, which was confirmed via XPS measurements. The enhanced piezoelectric constant (d(33) = 198 pC/N) and remanent polarisation (P-r=46.71 mu C/cm(2)) were obtained when x = 0.5.

Summary: Lanthanum borate glasses doped with Pr3+ were prepared and their physical and luminescence properties were studied. Suitable doping of Pr2O3 can enhance the glass density and molar volume, and the glass samples exhibit the strongest emission at 485 nm wavelength when excited by photons at 444 nm. The Judd-Ofelt parameters and CIE chromaticity coordinates were calculated to understand the surrounding environment of Pr3+ ions, suggesting the potential use of these glasses as light sources in yellow-orange-emitting devices.

Summary: A comparative study was conducted on PNZST/ZnO ceramic composites with different ratios, revealing that the lower ratio (x=0.1) composite exhibited a stable ferroelectric phase at room temperature, transitioning to an antiferroelectric phase upon heating, contributing to the pyroelectric effect. In contrast, the higher ratio (x=0.4) composite showed the presence of Zn2SnO4, leading to the decomposition of the ferroelectric matrix phase and consequently lower pyroelectric coefficient.

Summary: In two antiferroelectric ceramic compositions with comparable recoverable energy densities, the ceramic with a large hysteresis demonstrated a significant decrease in recoverable energy density and energy efficiency during test cycles, while the ceramic with a small hysteresis only showed minor degradation in energy density. These results indicate that reducing electric hysteresis in antiferroelectric capacitors is crucial for improving energy efficiency and extending service lifetime.
