All samples were calcined in the range of 900 °C–1100 °C for 2 h and sintered in the range of 1175 °C–1275 °C for 2 h. A pure ferrite phase was found in the powders calcined above 1000 °C and the average particle size of NZFO powders was increased from 0.39 µm to 0.59 µm when the calcination temperature was increased. The x-ray diffraction (XRD) analysis results confirmed the formation of pure spinel structure with cubic phase in all the ceramic samples. The average grain size (5.54–2.80 µm) was slightly decreased, and the dielectric constant (239–13) tended to decrease with increasing sintering temperature. As the sintering temperature increased to 1250 °C, it was found that the lattice parameters (8.366–8.387 Å), the density (5.29–5.35 g/cm3), and saturation magnetization (81.51–93.92 emu/g) tended to increase after that decrease.Keywords: NZFOsolid-state combustion techniquephase structuremicrostructuremagnetic properties AcknowledgmentsThe authors thank the Department of Physics, Faculty of Science, Naresuan University for their supporting facilities.

The Er3+ doping content was fixed at 1% and Yb3+ ion content was designated at 2, 4, 6, 8, and 10%. To study the relevant properties of the prepared samples, XRD, FE-SEM, FTIR, DRS, and UV-visible spectrometry were employed to characterize their morphology, crystal structure, functional group, energy gap, and photocatalytic degradation, respectively. The experimental results show that Yb ion incorporation has a significant effect on the decrease in its particle size and the change in morphology and the monoclinic-to-tetragonal phase change of the sample. The DRS result exhibits two extinct absorption edges belonging to the monoclinic and tetragonal phases, accompanying the characteristic absorption due to energy transitions of both Er3+ and Yb3+. The incorporation of Yb3+ ion with certain content exhibits noticeable enhancement in the photocatalytic performance of the Er-doped BiVO4 catalyst under the visible light illumination, which may be a result of the significant increase in the active surface area, increasing charge separation of mixed phases and possible up-conversion process.Keywords: Er-doped bismuth vanadateYb dopantphotocatalytic activity AcknowledgmentsThe authors would like to thank College of Materials Innovation and Technology, King Mongkut’s Institute of Technology Ladkrabang (KMITL) for characterization facility support.Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis research grant is supported by King Mongkut’s Institute of Technology Ladkrabang [Grant No. RE-KRIS/021/64].","PeriodicalId":13686,"journal":{"name":"Integrated Ferroelectrics","volume":"27 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136261999","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}

Firstly, the chemical compositions of glasses were varied by changing alkali fluoride (LiF and NaF), whereas the concentration of Er3+ was fixed at 1.00 mol%. The optical absorption pattern and intensity were resemblance. Broadband 1.53 μm emission was one prominent peak of Er3+ in glass and the highest emission intensity was obtained for NaF glass under the stimulating at 521 nm. Secondly, the NaF glass was prepared by variation of Er3+ concentration (0.1, 0.5, 1.0, 2.0, and 4.0 mol%). The emission intensity of glasses increases with an increase in Er2O3 concentration up to 2.00 mol% and decreases for higher Er2O3 concentration, because of the concentration quenching effect. Broadband emission was observed that it covers three telecommunication windows: S, C, and L bands. The absorption and emission cross-section of 2.00 mol% of Er3+ doped alkali oxyfluorophosphate were found to be 1.3895 x 10−20 cm2 and 1.7248 x 1020 cm−2, respectively by using the McCumber theory. Both values led to the estimate of the internal gain coefficient for 4I13/2→4I15/2 emission transition. The gain coefficient is positive when P is higher than 40%.

The phase evolution, microstructure, dielectric, ferroelectric and energy storage properties were examined. The BNT-BT-NBN powders and ceramics were calcined and sintered between 650–900 °C and 1100–1175 °C, respectively, for 2 h. All samples showed a typical perovskite structure, as revealed by X-ray diffraction. The Rietveld refinement analysis of the ceramics suggested the samples sintered between 1100 and 1150 °C had coexisting R + T phases, while the R + T+C phases were observed in the ceramics sintered at 1175 °C. The average grain size of the samples increased from 0.52 to 1.39 μm with increased sintering temperature. The density of the ceramics increased from 5.12 to 5.45 g/cm3 when the sintering temperature increased from 1100 to 1150 °C, and then decreased. Increasing the sintering temperature from 1100 to 1150 °C caused the dielectric constant at Ts (εs) and the dielectric constant at Tm (εm) to increase from 1727 to 1945 and 1564 to 1750, respectively, and then εs and εm declined. All BNT-BT-NBN ceramics had good dielectric temperature stability with only a±10% change when the temperature ranged from room temperature to ∼300 °C. The optimum energy-storage properties (Wrec = 0.62 J/cm3 and η = 83.2%) were obtained from the BNT-BT-NBN ceramics sintered at 1150 °C for 2 h.

The crystal structure, dielectric, ferroelectric and piezoelectric properties were systematically investigated with respect to the amount of Na excess. X-ray diffraction data identified pure perovskite structure for all compositions. The pseudocubic structure was observed for x = 0.0 − 0.005 before it transformed to rhombohedral structure at x ≥ 0.015. The grain size tended to be larger with increasing Na excess amount. Increasing x also led to a substantial increase in ferroelectric-relaxor transition temperature (TF-R) from 80 °C (x = 0) to 110 °C (x = 0.020). With increasing x from 0 to 0.020, the standard polarization-electric field (P-E) hysteresis measurements revealed a reduction in remanent polarization (Pr) together with an increase in coercive field (Ec), which was further confirmed by the remanent P-E hysteresis measurements. In addition, the piezoelectric constant (d33) was also found to steadily decrease as x increased. The observation of increased TF-R and Ec along with a decrease in d33 and Pr indicated a stabilization of ferroelectric order induced by Na excess.
