However, the existence of the antiferroelectric P phase at room temperature causes large hysteresis, resulting in reduced energy storage efficiency. In this study, 0.88NaNbO3–0.12Sr0.7Bi0.2TiO3 ceramics doped with Nd3+ (i.e., 0.88Na1-3xNdxNbO3-0.12Sr0.7Bi0.2TiO3) at x = 0.0 − 0.025 were prepared via conventional solid-state mixed oxide route. The XRD data showed that all samples exhibited an orthorhombic structure. With increasing Nd3+ doping content, the antiferroelectric P (Pbma) phase to R (Pnma) phase transition temperature (TP-R) shifted to lower temperatures. Consistent with the dielectric properties, a transition to a relaxor-like slim P-E loop indicative of an AFE R phase was observed at the composition x ≥ 0.01. This led to an increase in both the recoverable energy-storage density (Wrec) and efficiency (η) with an increasing amount of Nd3+ doping level. The maximum recoverable energy storage density (Wrec = 0.54 J/cm3) and high energy storage efficiency (η = 93%) were observed at x = 0.025 under an applied electric field of 100 kV/cm. In addition, the optimum composition at x = 0.025 also exhibited excellent temperature stability from 25 °C to 150 °C. This research demonstrates that the NN–SBT–xNd system has the potential for use for high-energy-density pulsed power capacitor applications.Keywords: Lead-free ceramicsNaNbO3energy storage properties Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was financially supported by The National Science, Research and Innovation Fund (NSRF) through Naresuan University (R2565B059).","PeriodicalId":13686,"journal":{"name":"Integrated Ferroelectrics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135195394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of BSN substitution on the phase formation, microstructure, dielectric, ferroelectric and energy storage properties of the BNBLT ceramics was investigated. With the substitution of BSN, the coexisting rhombohedral (R) and tetragonal (T) phases transformed into coexisting R and cubic (C) phase, verified by Rietveld refinement. The C phase increased with increased BSN content. The average grain size decreased from 1.14 to 0.89 µm when x increased to 0.03 and then increased to 0.96 µm. The measured density and maximum dielectric constant (εm) tended to increase from 5.44 to 5.87 g/cm3 and 1800 to 1942 when x increased to 0.03, then decreased to 5.25 g/cm3 and 1501, respectively.

Fatigue degradation and its practical applications are a significant problem in piezo/ferroelectric ceramics. Fatigue-induced domain orientations, physical damage or microcracking, and defects were studied using, X-ray diffraction (XRD), synchrotron X-ray absorption spectroscopy (XAS), and scanning electron microscope (SEM) techniques. The remnant polarization (Pr) decreased with the number of fatigue cycles, and the rate at which the decrease occurred was different for different fatigue temperatures. The weak and strong domain wall pinning effects played a major role in the Pr value with respect to the fatigue cycles. The sharp rise of Ec value at 5 × 103 cycles and the abrupt decrease of Ec values after 5 × 104 cycles could be due to the field screening effect and heat recovery of pinned domains. The abrupt decrease of Pr values after 5 × 105 cycles could be due to physical damage near the electrode interface region, and the same physical damage decreased with the increase in fatigue temperature.

The intense green emission at 544 nm was generated by the terbium 5D4 to 7F5 transition when excited with ultraviolet–visible (UV–Vis) light. The emission intensities of LNKBTb glasses increased with increasing terbium concentrations up to 4 mol%, after which they decreased, resulting in the concentration quenching effect, whereas decay time decreases as Tb2O3 content increases.

GIXRD, XANES, and EXAFS measurements were performed to analyze phase formation, crystal structure, and local structure of the films. The XANES data of the Hf L3-edge show no significant difference with respect to an increase in La content, indicating a considerable stability of the hafnium ion in the +4 oxidation state. Moreover, the EXAFS spectrum shows that the coordination number of Hf4+ is seven and the Hf–O bond length is ∼2.11 Å, which additionally confirms the formation of monoclinic HfO2 structure. The contributions of the second coordination shells, which are assigned to the Hf–Hf and Hf–La bonds, become well-structured with increasing La concentration in the HfO2 structure. However, the study suggests that the La-doped concentration affects the phase transformation from monoclinic to tetragonal and finally orthorhombic phase, leading to the presence of ferroelectric materials.Keywords: La-doped HfO2thin filmsphase transitionXANESEXAFS AcknowledgmentsThis work was supported by the Suranaree University of Technology (SUT) by Office of the Higher Education Commission under NRU Project of Thailand and Synchrotron Light Research Institute (Public Organization), SLRI, Thailand at BL 6A for all facilities and financial supports.
