Negative thermal expansion (NTE) is a notable physical property where a material’s volume decreases instead of increasing when heated. The identification of NTE materials is crucial for thermal expansion control engineering. Most NTE materials exhibit NTE only within a narrow temperature range, restricting their applications. Achieving NTE across a broad temperature range remains a significant challenge. This study developed a novel PbTiO 3 -based system, (1- x )PbTiO 3 – x BiLuO 3 , incorporating rare-earth elements, using a distinctive high-pressure and high-temperature synthesis technique. We achieved NTE across a broad temperature range by coupling lattice ( c / a ) with ferroelectric order parameters. The incorporation of BiLuO 3 resulted in distinctive ferroelectric characteristics, including increased tetragonality, spontaneous polarization, and NTE over a broad temperature range. NTE over an extended temperature range has been achieved in 0.95PbTiO 3 –0.05BiLuO 3 ( \(\overline{\alpha }_{{\text{V}}}\) = −1.7 × 10 –5 K −1 , 300–840 K) and 0.90PbTiO 3 –0.10BiLuO 3 ( \(\overline{\alpha }_{{\text{V}}}\) = −1.4 × 10 –5 K −1 , 300–860 K), compared to pristine PbTiO 3 ( \(\overline{\alpha }_{{\text{V}}}\) = −1.99 × 10 –5 K −1 , 300–763 K). The improved tetragonalities and broader NTE temperature range result from the strong hybridization of Pb/Bi–O and Ti/Lu–O atoms, as demonstrated by combined experimental and theoretical analyses, including high-energy synchrotron X-ray diffraction, Raman spectroscopy, and density functional theory calculations. This study introduces a novel example of NTE over a broad temperature range, highlighting its potential as a high-performance thermal expansion compensator. Additionally, it presents an effective method for incorporating rare-earth elements to achieve NTE in PbTiO 3 -based perovskites across a wide temperature range. Graphical abstract

The development of piezoelectric ceramics combining high piezoelectric response with excellent temperature stability has become increasingly crucial for advanced applications. In this work, the relaxor ferroelectric Pb(In 1/2 Nb 1/2 )O 3 was incorporated into BiScO 3 -PbTiO 3 system and successfully synthesized as 0.05Pb(In 1/2 Nb 1/2 )O 3 -(0.95- x )BiScO 3 - x PbTiO 3 (PIN-BS- x PT) ceramics by the conventional solid-state reaction. Systematic characterization of phase structure, microstructure and electrical properties reveals the formation of a morphotropic phase boundary at x = 0.59, which exhibits optimal electromechanical properties with piezoelectric coefficient d 33 = 522 pC/ N, Curie temperature T C = 402 °C and planar electromechanical coupling coefficient k p = 0.56. Remarkably, the PIN-BS-0.59PT ceramic demonstrates remarkable performance stability, achieving both high strain response (0.12 % at 20 kV/cm) and minimal temperature-dependent variation (13.5 % between 30 and 200 °C). Furthermore, the PIN-BS-0.59PT ceramic retains ～90 % of its initial d 33 value after annealing at 300 °C, demonstrating exceptional thermal depolarization resistance. These findings position PIN-BS- x PT ceramics as promising candidates for high-temperature piezoelectric applications.

In this work, based on the lanthanide rare earth Sm3+ doped 0.2Pb(Mg1/3Nb2/3)O3-(0.8-x)PbZrO3-xPbTiO3:0.015Sm ceramics with a rhombohedral-tetragonal morphotropic phase boundary (MPB) around x = 0.40, we gradually introduced alkaline earth Ba2+ and Sr2+ at the A-site to substitute Pb2+, namely, 0.2A(Mg1/3Nb2/3)O3-0.4AZrO3-0.4ATiO3:0.015Sm (A = Pb0.99-yBa0.01Sry) and conducted a systematic study on their phase structure, domain configuration, and electrical properties. The results indicate that without alkaline earth substituting, the MPB composition shows peak electrical property with piezoelectric coefficient d33 = 477 pC/N and electromechanical coupling factor kp = 0.59, while an appropriate amount of alkaline earth substituting changes the MPB from rhombohedral–tetragonal coexisting phases to rhombohedral–monoclinic–tetragonal coexisting phases, leading to a significant enhancement in electrical properties with d33 = 687 pC/N and kp = 0.63 around y = 0.03 for comparison. This work classifies the mechanism for alkaline earth substituting enhanced piezoelectric performance and may provide a guide for the development of high-performance lead-based relaxor ferroelectrics.

A novel xPb(Ni1/3Nb2/3)O3–(1-x)(0.30BiScO3–0.70PbTiO3) (PNN–BS–PT) ternary system was prepared by the columbite precursor method. The phase structure, microstructure, and electrical properties of ceramics of this system were investigated to identify the morphotropic phase boundary (MPB) composition of this system. The MPB with coexisting rhombohedral–tetragonal phases of PNN–BS–PT was located at approximately x=0.35, confirmed by their respective electric properties. With increasing PNN content, the coercive field EC, the Curie temperature TC, and the rhombohedral-to-tetragonal phase transition temperature TR–T were found to decrease and showed nearly linear dependences on their compositions. The enhanced properties were achieved in the MPB composition with x=0.35, which are as follows: dielectric constant εr=3160 (1 kHz), piezoelectric coefficient d33=490 pC/N, and electromechanical coupling factor kp=0.44. In addition, a large bipolar strain on the order of 0.6% was achieved for the composition when an electrical field E=40 kV/cm was applied.

Modern electronic devices are highly in demand for high-performance piezoelectric materials. Herein, Pb(Ni, Nb)O3–Pb(Lu, Nb)O3–PbTiO3 piezoelectric ceramics are investigated, among which the 0.52PNN–0.16PLN–0.32PT ceramic shows the best performance (d33 = 850 pC N−1, d33* = 1139 pm V−1). Excellent piezoelectricity can be explained by multiphase coexistence, as well as an enhanced local heterogeneous structure. Polar nanoregions that promote polarization rotation are an important cause of high piezoelectricity according to characterization using SEM and PFM. TEM also confirmed a heterogeneous domain configuration with two coexisting phases. In addition, a large signal piezoelectricity of 1000 pm V−1 is maintained in the temperature range of 20–90 °C. This work presents an excellent example of achieving both high piezoelectric properties and a good temperature range in relaxor ferroelectric ceramics.

An electrochemical sensor based on loading molecularly imprinted polymers (MIP) on the material surface can improve the specificity towards the object. In this work, a T-shaped PbTiO 3 with a high active-exposed (110) facet was prepared by a hydrothermal process. Then, Ag nanoparticles (Ag NPs) modified T-shaped PbTiO 3 was obtained by in-situ photocatalytic reduced method under UV irradiation , where a hetero-junction was formed with a well lattice matching between the (111) facet of Ag 0 and the (110) facet of PbTiO 3 . A MIPs modified by Ag nanoparticles (NPs)/PbTiO 3 (MAP) electrodes was prepared via electro polymerization process by o-Phenylenediamine (o-PD) in the presence of the template molecule, bovine hemoglobin (BHb), i.e., the detected molecule. The response peak current and concentration of BHb is demonstrated with a good linear relationship in the range of 0.00294–0.41 nM (R 2 =0.98), and the detection limit at 0.23 pM (S/N = 3). A heterojunction between Ag NPs and high- active facet of PbTiO 3 is beneficial to oxidizing electroactive material ([Fe (CN) 6 ] 3-/4- ), generating more BHb-imprinting cavities on the modified electrode and improving the sensitivity of sensor. The electrochemical sensor is with a simple, stable structure and high sensitivity to BHb detection. Furthermore, the sensor was successfully applied to detect BHb in the bovine serum samples.

The rational design and efficient utilization of room-temperature ferroelectric physical field photocatalysts are of significant importance for addressing energy and environmental challenges. In this work, ferroelectric-based Zn 0.5 Cd 0.5 S/PbTiO 3 S-scheme heterojunction photocatalyst was synthesized via a facile and mild two-step hydrothermal method. The heterostructure was constructed through in-situ selective growth of Zn₀.₅Cd₀.₅S nanoparticles onto the positively polarized surface of PbTiO₃ microplates. The underlying mechanism of this ferroelectric polarization-driven selective growth was systematically investigated through combined theoretical simulations and experimental analyses. Furthermore, the charge transfer behavior within the heterostructure, the synergistic enhancement mechanism of the built-in electric field, and the photocatalytic Cr(VI) reduction performance along with influencing factors were comprehensively examined via DFT calculations and a series of characterization techniques. Zn 0.5 Cd 0.5 S/PbTiO 3 S-scheme heterojunction catalyst integrates three key aspects for boosting photocatalytic efficiency, including the increased solar spectrum response, the enhanced photogenerated charge separation, and the improved surface chemical reaction. As a result, it exhibits an optimal Cr(VI) reduction rate of 15.16 μmol·min⁻¹ ·g⁻¹ , which is 5.5 times higher than that of pristine PbTiO₃. This provides a new design and application of the synergistic and enhanced effect on ferroelectric-based artificial-photosynthesized heterojunction catalyst.

Grain-oriented Pb(Mg 1/3 Nb 2/3 )O 3 -PbZrO 3 -PbTiO 3 (PMN-PZ-PT) based ceramics were synthesized through templated grain growth via using BaTiO 3 (BT) templates. Although BT templates are partially destroyed by PMN-PZ-PT matrix, CuO addition remarkably promotes [001] c -oriented grain growth behavior of the ceramics, resulting in an improvement of Lotgering factor F 001 from ~86% to 98%. Both crystallographic texture and CuO doping increase tetragonality and reduce average domain size of the ceramics dominated by rhombohedral phase. Consequently, 0.50 wt% CuO-doped ceramics ( F 001 ~98%) exhibit optimum electromechanical properties: d 33 ~860 pC/N, d 33 × g 33 ~48.6 × 10 −12 m 2 /N, k p ~0.80, E c ~7.2 kV/cm, tan δ ~0.8% and T c ~222 °C. In addition to ~3.7 times and 6.6 times higher d 33 and d 33 × g 33 , those ceramics possess about 240% enhanced piezoelectric strain and much better thermal stability ( S max / E max variation ≤2% between RT and 150 °C) relative to non-textured counterpart. This work offers a good paradigm for simultaneously exploring high piezoelectric response and good temperature stability in piezoceramics, benefiting the development of next-generation advanced electromechanical devices.

Piezoelectric ceramics with high strain response and low hysteresis are highly in demand for high-performance actuator applications. Unfortunately, the trade-off relationship between large field-induced strain and low hysteresis in piezoelectric ceramics is a key challenge for designing high-performance piezoelectric actuators. Herein, y mol%La-doped 0.10 Pb(In 1/2 Nb 1/2 )O 3 - x PbZrO 3 -(0.90 – x )PbTiO 3 [0.10PIN- x PZ-(0.90-x)PT: y mol%La] ternary relaxor ferroelectric ceramics were prepared by conventional solid-state reaction technique. Pb(In 1/2 Nb 1/2 )O 3 (PIN) as a relaxor end member was introduced into (Pb,La) (Zr,Ti)O 3 (PLZT) system to improve relaxor characteristics and strain properties. A giant strain of 0.23% was obtained in 0.10PIN-0.59PZ-0.31 PT: 8mol%La ceramic at the electric field of 20 kV/cm, with a high piezoelectric d 33 * of 1150 pm/V and low hysteresis H y of 6.4%, exhibiting a potential application in high-performance piezoelectric actuators. Furthermore, the effects of La ion doping and components on the ferroelectric, dielectric and electric field-induced strain properties were investigated, and provides a new way for improve the strain properties of piezoelectric materials .

Ferroelectric ceramic materials with large and temperature-insensitive strain responses are highly desired for the practical application of actuators in harsh environmental conditions. In this work, novel xBi(Mg1/2Zr1/2)O3–(0.55 − x)PbZrO3–0.45PbTiO3 (xBMZ-PZ-0.45PT) ternary ferroelectric ceramics were successfully fabricated by a solid-state reaction process. The phase structure of xBMZ-PZ-0.45PT ceramics gradually evolves from rhombohedral-tetragonal coexistence phases to rhombohedral phase with an increase in the BMZ content and the diffuse phase transition behavior becomes increasingly evident. The relaxation behavior is strongest for x = 0.35 composition. Pmax and Pr values first gradually increased, and then gradually decreased with increasing BMZ content, while Ec values display an increasing trend. A large strain response of 0.33% at 5 kV mm−1 was obtained in this ternary ferroelectric ceramics with x = 0.35, which can be attributed to the electric field-induced reversible ergodic relaxation phase to the ferroelectric phase transition. The strain was simultaneously temperature-insensitive with a slight decrease from 0.33% at 30 °C to 0.32% at 150 °C. The results indicate that BMZ-PZ-PT ternary ferroelectric ceramics are promising candidate materials for actuator applications in harsh environmental conditions.

Sm-doped Pb(Mg 1/3 Nb 2/3 )-PbTiO 3 (PMN-PT) binary ferroelectric ceramics has received extensive attention due to the excellent dielectric and piezoelectric properties . However, its Curie temperature ( T c ) is greatly reduced by Sm doping and T c is only 89 °C at the optimum piezoelectric coefficient. In this work, Sm-doped Pb(Mg 1/3 Nb 2/3 )O 3 –Pb(Zn 1/3 Nb 2/3 )-PbTiO 3 (Sm: PMN-PZN-PT) ternary ferroelectric ceramics near MPB were successfully manufactured and the crystal structure, microstructure and electric properties were investigated with respect to Sm doping content. A high piezoelectric coefficient of 870 pC/N and a high T c of 146 °C were achieved simultaneously in PMN-PZN-PT ternary ceramics with 1% Sm doping content. In addition, the room temperature dielectric constant was greatly improved by Sm doping and the P r , P s and E c values gradually decrease with the increase of Sm content. These results indicate that Sm-doped PMN-PZN-PT ceramics may be an attractive material for high performance piezoelectric device applications.

Piezoelectric materials have wide commercial applications involving our everyday lives. The common categorized “soft” and “hard” piezoelectric materials have distinct even contradictory performance parameters typically exemplified by piezoelectric coefficient d 33 and mechanical quality factor Q m . However, for some special devices operated in resonant mode, simultaneously high or at least balanced performance parameters are needed. Here, we show the transition from “soft” to “hard” performance in 2 mol% Sm doped (0.36- x )Pb(Ni 1/3 Nb 2/3 )O 3 - x Pb(Mn 1/3 Nb 2/3 )O 3 -0.28PbZrO 3 -0.36PbTiO 3 quaternary solid solution piezoceramics, for which the d 33 and planar electromechanical coupling factor k p decrease, while Q m and Curie temperature T c increase monotonously with increasing x value. As the results, balanced performance with moderate d 33 = 446 pC/N, k p = 0.49, Q m = 425, and T c = 170 °C are achieved around x = 0.03. This work not only shows the feasibility for combining “soft” and “hard” performance by forming appropriate solid solutions, but also provides a suitable material basis for further simultaneously optimizing piezoelectric parameters.
