AbstractLead-free 1-x(Bi0.47Na0.47Ba0.06)0.95La0.05TiO3-xBa(Sn0.70Nb0.24)O3 (BNBLT-xBSN) ceramics with x = 0, 0.01, 0.02, 0.03 and 0.04 mol.% were synthesized by the solid-state combustion technique with a calcination temperature of 750 °C for 2 h and a sintering temperature of 1150 °C for 2 h. 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. The remanent polarization (Pr) and coercive field (Ec) decreased when x increased to 0.03. The 0.97BNBLT-0.03BSN ceramic exhibited the lowest energy loss density (Wloss ∼ 0.10 J/cm3) and the highest energy-storage efficiency (η ∼ 77.3%) measured under an electric field of 70 kV/cm.Keywords: BNBLT-xBSNcombustiondielectricferroelectricenergy storage AcknowledgmentsThe authors thank the Department of Physics, Faculty of Science, Naresuan University for their supporting facilities.

AbstractThis paper presents the effect of temperature on the electrical fatigue behavior of barium calcium zirconate titanate (Ba0.85Ca0.15Zr0.1Ti0.9O3) ceramics. 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 near-edge X-ray absorption fine structure (NEXAFS) study was utilized to evaluate the oxygen-related defect concentration.Keywords: Lead-free ceramicstemperature-dependent fatigueoxygen defectsdepolarization of domainsNEXAFS AcknowledgmentsDr. Julia Glaum, Department of Materials Science and Engineering, Norwegian University of Science and Technology, Norway, is acknowledged for her useful discussion.

AbstractThe melt-quenching approach was implemented to create terbium-doped lithium sodium potassium borate glasses (LNKBTb). Archimedes’ principle, absorption and luminescence spectra, including CIE chromaticity were used to characterize the properties of glasses. Terbium in glasses absorbs photon in the visible and near infrared ranges. 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. In CIE 1931, the overall color of emission is green.

摘要采用熔体淬火法制备掺铽硼酸锂钠钾玻璃(LNKBTb)。利用阿基米德原理、吸收光谱和发光光谱，包括CIE色度来表征玻璃的性质。玻璃中的铽吸收可见光和近红外范围内的光子。在紫外-可见(UV-Vis)光激发下，铽5D4向7F5跃迁，在544 nm处产生了强烈的绿色辐射。当Tb2O3含量达到4mol %时，LNKBTb玻璃的发射强度随浓度的增加而增加，之后发射强度下降，导致浓度猝灭效应，而衰减时间随Tb2O3含量的增加而缩短。在CIE 1931中，发射的整体颜色为绿色。可带来可继续发展用作绿色光源和激光器中的光子材料。作者要感谢玻璃技术和材料科学卓越中心研究实验室的所有研究生和合作研究人员，还有Rajamangala理工大学工业材料科学系。披露声明作者未报告潜在的利益冲突。本项目由泰国国家研究委员会(NRCT)资助(合同编号:N41A650404)和CERNTEK COMPANY LIMITED。

AbstractLead-free multiferroic composite ceramics of 0.7BaTiO3-0.3Ni0.7Zn0.3Fe2O4 (BT-NZF) were prepared by the solid-state combustion technique. The BT and NZF powders were calcined in the range of 1100 to 1200 °C for 4 h and 900 to 1100 °C for 2 h, respectively. Afterward, BT-NZF composite ceramics were sintered between 1100 and 1250 °C for 4 h. The effect of the firing temperature on the phase formation, microstructure, electrical, and magnetic properties of BT-NZF composite ceramics was investigated. X-ray diffraction of BT and NFZ powders showed the highest purity phase were prepared the calcination temperatures of 1100 and 1050 °C, respectively. The BT-NZF composite ceramics exhibited coexisting tetragonal perovskite and cubic spinel phases. The maximum density of 5.85 g/cm3 was obtained when sintering the composite ceramics at 1125 °C. The dielectric constant at room temperature increased with increased sintering temperature. The hysteresis loops showed leakage current in all samples. Ferromagnetic properties showed the highest Ms ∼ 24.56 emu/g measured under a magnetic field of 10,000 Oe from the sample sintered at 1150 °C.Keywords: BT-NZFcompositesmultiferroicferroelectricferromagnetic AcknowledgmentsThis project is funded by National Research Council of Thailand (NRCT): (N41A650100), Naresuan University (NU) and National Science, Research and Innovation Fund (NSRF) with Grant No. R2565B059.

AbstractFor this article, waste glass cullet obtained from the glass industry was used as a choice of SiO2 substitute in glass manufacturing. A series of soda lime silicate glasses doped with CuO, in composition (55−x) SiO2: 15Li2O: 20Na2O: 10CaO: xCuO (x = 0.00, 0.01, 0.02, 0.03, 0.04, and 0.05 mol%)) were prepared by melt-quenching technique. The parameters such as density and molar volume were measured and evaluated their oscillator strength, refractive index, ion concentration, polaron radius, and inter-nuclear distance. Optical properties such as refractive index, absorption spectra, optical band gab, and CIE L*a*b* were investigated. With increasing of CuO concentration, the density and the refractive index of glasses increased, while the molar volume decreased. The absorption spectra show board peak in the range of 550 to 950 nm. The addition of CuO generated the blue hue in glasses, corresponding to the CIE L*a*b color coordinate.Keywords: Waste glassculletsoda lime silicateglassCuO AcknowledgmentsThe research team would like to thank the Nakhon Pathom Rajabhat University Research Center of Excellence in Glass Technology and Materials Science for providing tools and equipment as well as facilitating research operations.Disclosure StatementNo potential conflict of interest was reported by the author(s).

AbstractSodium niobate (NaNbO3)-based antiferroelectric (AFE) ceramics have received significant attention for energy storage applications because of their good performance, low cost, and nontoxicity. 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).

AbstractThe glass samples (35-x)B2O3:35SiO2:12Na2O:7.9CaO:0.1Sb2O3:10BaO:xCr2O3 with a variation of Cr2O3 content were successfully fabricated and characterized for solid-state lighting material applications. The results showed the most suitable composition within the range of study at 0.02 mol% of Cr2O3. This composition gave higher reflection loss (RL), lower oxide polarizability, and lower molar refractivity. The Commission International de I'Eclairage (CIE) chromaticity coordinates confirmed a strong orange color emission. Hence, this suggests that the 0.02 mol% Cr2O3 glass is a good candidate and cost-effective for orange-emitting solid-state lighting material applications. This study will be a useful literature source for further development in this field.Keywords: Borosilicate glassCr2O3 concentrationluminescence propertiesTanabe–Sugano diagram AcknowledgmentsJ.

The results showed the most suitable composition within the range of study at 0.02 mol% of Cr2O3. This composition gave higher reflection loss (RL), lower oxide polarizability, and lower molar refractivity. The Commission International de I'Eclairage (CIE) chromaticity coordinates confirmed a strong orange color emission. Hence, this suggests that the 0.02 mol% Cr2O3 glass is a good candidate and cost-effective for orange-emitting solid-state lighting material applications.

AbstractHfO2-based films prepared by the integration of the sol-gel method and spin-coating procedure were used as the study system to investigate the influence of La doping by varying the La contents of 20, 40, 50, and 60 wt%. 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.

AbstractIn this study, the phase formation, microstructure, and electrical properties of Sr0.3(Bi0.70Na0.67Li0.03)0.5(Ti1-xNbx)O3: SBNLT-Nbx lead-free ceramics synthesized via the solid state combustion technique were examined. SBNLT-Nbx ceramics with various Nb content of x = 0, 0.01, 0.03, and 0.05 were calcined at 750 °C and sintered at 1175 °C for 2 h, respectively. The SBNLT-Nbx calcined powders showed a perovskite structure and a secondary NbO2 phase was observed with Nb5+ content of 0.03 and 0.05 mol%. All SBNLT-Nbx ceramics exhibited a pure perovskite phase with coexisting rhombohedral and tetragonal phases. The grain size was in the range of 1.17-1.34 µm. The εmax and tan δmax tended to decrease with increased x content. The best ferroelectric and energy storage properties (Pmax = 27.45 µC/cm2, Pr = 1.92 µC/cm2 and Wtotal = 0.958 J/cm3, Wrec = 0.739 J/cm3, Wloss = 0.219 J/cm3, η = 77.1%), measured under an electric field of 70 kV/cm, were observed at x = 0.01.Keywords: SBNLTdielectricferroelectricenergy storagecombustion technique Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by Naresuan University (R2566C005).

Abstract(Ba0.704Sr0.176Bi0.12)1-xZn0.08Nb0.04Ti0.88O3-Nax (BSBZNT-xNa) ceramics with x = 0, 0.01, 0.03 and 0.05 mol%, were prepared by the solid-state combustion technique. The samples were calcined and sintered at 950 °C and 1375 °C, respectively, for 2 h. The phase, microstructure, dielectric, ferroelectric and energy storage properties were investigated. The X-ray diffraction patterns of the BSBZNT-xNa powders showed a perovskite phase for all samples. When x increased from 0-0.03, the average particle size increased from 380 to 480 nm, then decreased to 420 nm. All sintered samples showed the coexistence of the orthorhombic and cubic phases. The average grain size was in the range of 2.03 to 1.39 µm. The BSBZNT-0.01Na ceramic exhibited the highest dielectric properties at room temperature (ɛr = 902, tanδ = 0.10), the lowest remanent polarization (Pr = 0.10 µC/cm2), coercive field (Ec = 0.43 kV/cm), and the highest energy storage efficiency (η ∼ 94.70%) measured under an electric field of 70 kV/cm.Keywords: BSBZNT-xNa ceramicsolid-state combustionphase structuremicrostructureenergy storage AcknowledgmentsThe authors wish thank the Department of Physics, Facullty of Science, Nareasuan University for provision of supporting facilities.
