A ternary solid solution (0.935–x)Bi_0.5Na_0.5TiO₃–0.065BaTiO₃–xSrTiO₃ (BNBST, BNBSTx), reported in our previous work, that exhibits a large strain response at a critical composition, was investigated with the emphasis on its bipolar fatigue behavior. The results indicated that BNBST with a high SrTiO₃ content owning an ergodic relaxor state exhibited fatigue-free behavior after 10⁶ cycles. Furthermore, unexpected almost fatigue-free behavior was also observed in BNBST with a low SrTiO₃ concentration which has a typical ferroelectric long-range order. The excellent fatigue properties are quite favorable for practical applications.

Self-assembly ordered domain configurations serve the high electromechanical response lead-free thin films
2024, Journal of the European Ceramic Society
Micro-electromechanical systems (MEMS) urgently require high-performance lead-free piezoelectric thin films, which is rather difficult to achieve via the existing strategy of designing a morphotropic phase boundary. How to update the optimization methods for piezoelectric performance is a challenge. Here, we proposed a simple and interesting way, that is, constructing the self-assembly ordered domain configurations in our oriented lead-free thin films. Driven by the local strain, we realized a periodic arrangement of disordered nano-domains and ordered striped domain structures, and thus obtained an outstanding electrostrain of 1.55%. Multi-scale characterization and phase-field simulations suggest the underlying mechanism of this giant strain as the synergy between the high polarization brought about by the periodic nano-pillar-like striped domains, the highly sensitive electrical stimulation response of defective dipoles and disordered nano-domains. The presented high electrostrain supports the potential MEMS application, the proposed optimization strategy serves the next generation lead-free thin films with higher electromechanical response.
KNN+Nb<inf>2</inf>O<inf>5</inf> co-modified BNBST-based relaxor ferroelectric ceramics for X8R energy storage capacitors
2023, Ceramics International
Environmentally friendly ceramics with high dielectric temperature stability and excellent energy storage properties are desired for next generation low-voltage driven pulsed power supply systems. Herein, (Bi_0.5Na_0.5)_0.65(Ba_0.3Sr_0.7)_0.35(Ti_0.98Ce_0.02)O₃+x wt% K_0.5Na_0.5NbO₃ (KNN) + y wt% Nb₂O₅ (abbreviated as BNBSTC + K_xN_y) lead-free relaxor ferroelectric ceramics are prepared to investigate the effect of KNN + Nb₂O₅ co-modification on the structure and dielectric energy storage properties. In optimized BNBSTC + K₈N₈ ceramics, a medium high ε_r = 1310 with low tanδ = 5 × 10⁻³ (@25 °C & 1 kHz) meeting the EIA X8R standard can be achieved in addition to a recoverable energy storage density W_rec = 0.92 J/cm³ with high efficiency η = 93% only at a low electric field of 100 kV/cm. Moreover, the BNBSTC + K₈N₈ ceramics exhibits excellent energy storage stability under different frequency, fatigue cycle and temperature testing environments, showing an attractive prospect in low-voltage driven X8R dielectric energy storage capacitors.
Effect of introducing Sr2+/Hf4+ on phase structures, bandgaps, and energy storage performance in Bi<inf>0.47</inf>Na<inf>0.47</inf>Ba<inf>0.06</inf>TiO<inf>3</inf>-based ferroelectric ceramic
2023, Ceramics International
Dielectric energy storage ceramic capacitors have garnered wide attraction in recent years due to their splendid integrated energy storage properties. However, difficulties in obtaining splendid integrated properties limit their industrial application. This work achieved splendid integrated energy storage properties by doping Sr²⁺/Hf⁴⁺ into the Bi_0.47Na_0.47Ba_0.06TiO₃ ceramics. The R3c and P4bm phases were simultaneously induced and the short-range ordered polar nanoregions were formed, thereby generating a large polarization D-value by maintaining the large maximum polarization of the Bi_0.47Na_0.47Ba_0.06TiO₃ ceramics and greatly reducing the remnant polarization. By increasing both the density of the grain boundaries and the difficulty of electrons leaping out of the valence band to the conduction band, the breakdown electric fields of the ceramics were greatly improved. Eventually, a high W_rec of 5.83 J/cm³, a moderate η of 83.67%, a stable frequency (W_rec ≈ 2.84 ± 2.1% J/cm³, η ≈ 80.7 ± 2.8%, 1–200 Hz), excellent temperature stability (W_rec ≈ 2.89 ± 1.4% J/cm³, η ≈ 83.7 ± 1.0%, 20–140 °C), and a fast discharge rate (8 μs) were simultaneously obtained in the 0.8Bi_0.47Na_0.47Ba_0.06TiO₃-0.2SrHfO₃ relaxor ferroelectric ceramics. These results suggested that the co-doping of A/B sites could significantly improve the energy storage properties of the Bi_0.47Na_0.47Ba_0.06TiO₃ ceramics. Furthermore, the excellent integrated properties indicate that the 0.8Bi_0.47Na_0.47Ba_0.06TiO₃-0.2SrHfO₃ ceramics are expected to meet the application requirements of dielectric capacitors under complex conditions in the future.
Enhanced energy storage properties and excellent fatigue resistance of Pb-free Bi<inf>0.47</inf>Na<inf>0.376</inf>K<inf>0.094</inf>Ba<inf>0.06</inf>Nb<inf>0.024</inf>Ti<inf>0.97−x</inf>(Ta<inf>0.24</inf>Sn<inf>0.7</inf>)<inf>x</inf>O<inf>3</inf> relaxor ceramics
2022, Journal of Alloys and Compounds
Pb-free Bi_0.47Na_0.376K_0.094Ba_0.06Nb_0.024Ti_0.97−x(Ta_0.24Sn_0.7)_xO₃ perovskite ceramics were prepared using a mixed-oxide reaction technique, and their structural, dielectric, ferroelectric, and energy storage properties were systematically investigated. All the compositions exhibited a pseudo-cubic perovskite crystal structure with a highly dense morphology. The doping of complex ions (Ta_0.24Sn_0.7)⁴⁺ disturbed the long-range ordering, which reduced the ferroelectric-to-relaxor phase transition temperature to room temperature. Hence, the modified ceramics exhibited relaxor behavior in their polarization and current density versus applied field plots. Owing to the excellent field-induced ferroelectricity and facile reversibility of ferroelectric-relaxor phase transition of polar nanoregions (PNRs), a high recoverable energy density of 1.65 J/cm³ with a good efficiency of 77.69% was achieved under 125 kV/cm at x = 0.03. In addition, the ceramic with x = 0.03 showed a high recoverable energy density of 1.01 J/cm³ with a high conversion efficiency of 84.22% at 70 °C under 80 kV/cm and fatigue-free characteristics during 10⁵ cycles, demonstrating the highly dynamic and very stable nature of PNRs and very few ionic defects in the grains. Therefore, such ceramics (x = 0.03) are expected to be suitable for high-energy-density materials in electronic industries.
Boltzmann vs. non-Boltzmann (non-linear) thermometry - Yb3+-Er3+ activated dual-mode thermometer and phase transition sensor via second harmonic generation
2022, Journal of Alloys and Compounds
Second harmonic generation (SHG) and upconversion luminescence (UCL), as second-order nonlinear optical (NLO) effects, are crucial in modern optics and optoelectronics. Here, through the chemical engineering process we obtained a series of optically active BaTiO₃: Er³⁺, Yb³⁺ perovskite materials, exhibiting temperature-dependent NLO responses. Upon 976 nm laser light irradiation, the micron-sized, polycrystalline samples show simultaneously intense UCL and SHG effects. Comparison of the thermometric features based on luminescence thermometry, i.e., band intensity ratio based on thermally-coupled levels of Er³⁺, and NLO thermometry, i.e., SHG/UCL intensity ratio, shows that the superior thermal sensitivity (≈ 4%/K, at ~400 K) and excellent temperature resolution ( $δ$ T = 0.07 K) is achieved for the NLO thermometry approach. Furthermore, the combination of NLO spectroscopy with UCL allows rapid, more precise and clear phase transition detection (from tetragonal to cubic phase at around 386 K), compared to conventional structural methods, such as X-ray diffraction and Raman spectroscopy. Our work suggests that some non-Boltzmann, non-linear thermometers can provide much more effective temperature readouts (compared to the commonly studied Boltzmann thermometers), simultaneously working as accurate, rapid and non-invasive phase transition sensors.
Giant strain with ultra-low hysteresis by tailoring relaxor temperature and PNRs dynamic in BNT-based lead-free piezoelectric ceramics
2022, Ceramics International
State-of-the-art ferroelectric materials with large field-induced strain together with low hysteresis are required in high precision or positioning devices. However, the high electro-strain is always suffered from a large strain hysteresis, severely restricting its practical application. In this study, the relaxor temperature (T_f) of BNT-6BT near the morphotropic phase boundary with initially high polarization was adjusted to near room temperature by adding Sr_0.7La_0.2TiO₃. The room temperature relaxation properties feature with the high dynamic polar nanoregions with moderate polar spatial correlations, which paired the high strain (0.325%) and ultra-low hysteresis (8.02%). This actuation strain is superior to those of previously reported lead-free piezoelectric materials. Meanwhile, the strain responses also displayed outstanding temperature and frequency stability from 30°C to 150 °C and 1 Hz–25 Hz, respectively, indicating its practical application potential. The results will provide new insight into the design of high-performance BNT-based ceramics for use in actuators.
