Summary: This study demonstrates the electrically modulated photoluminescence (PL) in ferroelectric ceramics, which allows for tunable PL with high repeatability, flexibility, and faster response. The distortion of structural symmetry under an external electric field enables the emergence of new channels for radiative and/or forbidden transitions, providing innovative opportunities for designing advanced light switching devices.

Summary: The electrocaloric properties of commercially modified Pb(Zr,Ti)O-3- (PZT)-based soft and hard ceramics were investigated. Both positive and negative electrocaloric temperature change were observed in all ceramics. The negative electrocaloric effect was related to the phase transition in PZT ceramics, while the positive effect was observed in both soft and hard ceramics.

Summary: Rare earth doped ferroelectric ceramics, such as the x% mol Sm3+ doped BaTiO3 (BTO:xSm3+) ceramics studied in this research, have shown great potential for multifunctional optical-electro devices. The effect of Sm3+ ions composition on the phase structure, ferroelectric, energy storage, and photoluminescence properties were investigated. The results indicate that the addition of Sm3+ ions leads to a decrease in remanent polarization, but a significant increase in energy storage density and efficiency. The ceramics also exhibit a broader temperature transition range and a lower Curie temperature, making them suitable for optoelectronic device design.

Summary: The photoluminescence properties of Dy3+ doped Na0.5Bi0.5TiO3 lead-free ferroelectric ceramics were systematically studied, showing strong emission under a specific excitation wavelength suitable for warm white light. The ceramic exhibits optimal luminous performance at a Dy3+ content of 0.012, but experiences significant thermal quenching of luminous intensity at temperatures above 293 K.

Summary: Under the application of an external voltage, high electric field concentrations develop around the interdigitated electrode edges inside multilayer ceramic actuators (MLCAs). The local inhomogeneity in the electromechanical response is caused by the spatial distribution of the local electrical field. By utilizing synchrotron-based high-energy X-ray diffraction (XRD), the structural changes in partially electroded Nb-doped PbZrxTi1-xO3 samples as a function of applied electric field were investigated. The results show that the domain switching behavior and phase transitions are spatially dependent across the inactive regions in partially electroded samples, especially near the electrode edge and the tetragonal composition near the morphotropic phase boundary (MPB).

Summary: The study presents a novel approach for electroceramics by utilizing precipitates to pin domain walls, improving piezoelectric properties and enhancing mechanical quality factor. This new method reduces hysteresis in electrostrain while slightly increasing the piezoelectric coefficient and electromechanical coupling factor. The process can be smoothly implemented in industrial production and easily optimized in laboratory settings for various ferroelectric systems.

Summary: In our work, lead-free ferroelectric ceramics based on (1-x) (0.935BNT-0.065BaTiO3)-xSrRECoO4 (BNBT6.5-xSREC, RE = Pr, Eu, Sm) were prepared, exhibiting large electrostrain and photoluminescence effect. By introducing SREC dopant into BNBT6.5, the long-range ferroelectric order of ceramics was disrupted, resulting in a weak polar state dominated by polar nanoregions. The electrostrain was greatly promoted due to the reversible transition of PNRs under the electric field. When the content of SREC was 0.012, large field-induced strains of 0.38-0.44% were obtained, equivalent to a large signal d33* (Smax/Emax) of 543-586 pm/V. The modified ceramics showed strong photoluminescence with bright red or orange emissions, depending on the type of RE elements, relying on the luminescence effect of RE3+ ions in SREC. However, the strong emission was strongly quenched in samples with a higher SREC content due to the photoluminescence quenching effect of Co3+ ions in the SREC dopant. The quenching model can be attributed to the formation of non-radiative recombination centers induced by Co3+ ions, which affect the energy transition of RE3+ ions from the excited state to the ground state.

Summary: Er3+-doped KNN-SYT transparent ferroelectric ceramics were successfully prepared by pressureless sintering method. The doping of Er3+ does not change the structure of the ceramic and Er3+-doped ceramics exhibit excellent upconversion luminescence properties, thanks to the presence of Yb3+ causing continuous energy transfer. These ceramics also maintain good optical transparency and electrical properties at lower Er3+ content.

Summary: This article introduces a simple mechanism using a monolithic, bandgap-engineered photoferroelectric ceramic to blindly measure the wavelength and intensity of incident light. The photoferroelectric compound, Ba- and Ni-doped (K, Na)NbO3, exhibits a direct bandgap of approximately 2 eV and a spontaneous polarization of approximately 0.25 C m(-2), allowing reliable distinction of wavelengths and power density. The proposed alternative offers filterless, wavelength-selective photodetection and color sensing.

Summary: The study investigates the piezoelectric hard/soft effects of multivalence co-dopants (Sb and Mn) in PZT ceramics, revealing that the charge compensation mechanism between Sb3+ ions substituting Pb2+ at the A-sites and Mn2+ ions localized at the B-sites influences the material properties. The findings suggest that the interplay between multiple valence states and locations of the co-dopants, along with the charge compensation mechanisms, significantly affect the piezoelectric behavior of the material.

Summary: Recent studies have demonstrated the importance of the chemical composition and shape of magnetic nanoparticles in determining their properties. In this study, we synthesized cube-like nanoparticles and bimagnetic nanocomposites using an eco-friendly co-precipitation method. The nanocomposites exhibited good exchange-coupling interaction between the hard and soft magnetic phases, resulting in enhanced saturation magnetization. These materials showed promise for use in magnetic hyperthermia.
