AbstractThe conventional melt quenching procedures were followed to fabricate the samples of ZnO-BaO-B2O3-TeO2 (ZBBoT) glass doped with various concentration of Tm2O3. The consequent properties which feasible depend on the dopant were examined: density, molar volume, refractive index, absorption, and photoluminescence. The Judd-Ofelt (J-O) parameters (Ωλ, λ = 2, 4, and 6) were calculated using the absorption spectra and provided the trend of Ω2 > Ω6 > Ω4. These parameters were eventually processed to investigate the properties reflecting the appropriateness of this type of glass for optical applications. The emission spectra individually provide 2 peaks at 454, and 478 nm which are used in several optical devices.Keywords: Thulium oxideboro-tellurite glassluminescenceJ-O parametersZBBoT AcknowledgmentsThe authors would like to thank Thepsatri Rajabhat University for its warm support and Nakornpathom Rajabhat University for its fabulous facilities.

AbstractIn this study, the effect of firing temperatures on phase formation, microstructure dielectric and magnetic properties of Ni0.6Zn0.4Fe2O4 (NZFO) ceramics were investigated. The NZFO powder were synthesized by the solid-state combustion technique using glycine as a fuel to reduce the reaction temperature. 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.

AbstractThe Na2O:Al2O3:Gd2O3:P2O5 glasses were doped with different concentrations of Sm3+ ions and synthesized by the melt-quenching technique. These glasses were investigated to characterize physical and spectroscopy analyses that have been carried out by density, molar volume, absorption, FTIR, and photoluminescence measurements. The density and molar volume of glasses increases with the addition of Sm2O3 concentration. Glasses absorbed photons in UV, VIS, and NIR regions. The strong orange emission via the 4G5/2 to 6H7/2 radiation transition of Sm3+ was generated under 275 and 402 nm excitation. The glass has an interesting potential photonic application.Keywords: SamariumEnergy TransferLuminescence Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingO.

Abstract The zinc bismuth borate (ZBB)glasses have been calculated using Phy-X program at the Compton energy range. The ZBB glasses were decided in the concentration of Bi2O3 = 25, 30, 35 and 40 mol%. The mass attenuation coefficient, the effective atomic number, the effective electron density, the half value layer and the lead equivalent thickness were investigated. The results show the trend of values were decrease when the Compton energy increasing and found the values were higher when the concentration of Bi2O3 increases. The Zeff and Neff show similar trend showing that the values decrease with decrease in Bi2O3 content. The HVL value shows lowest with an increase in concentration of Bi2O3 suggesting their role to be good candidature for radiation shielding material applications. The lead equivalent thickness of glass samples shows a good trend when adding more concentration of Bi2O3 and found the highest value at 40 mol% of Bi2O3 concentration.

Abstract This work aims to investigate the effects of CuO doping (0–1.0 wt%) on the local structure of (Ba0.85Ca0.15)(Ti0.90Zr0.10)O3 (BCTZ) ceramics. These samples were prepared via the solid state combustion technique using glycine as fuel. The local structure of the samples was characterized by XANES (X-Ray Absorption Near-edge Structure) spectroscopy. The Cu, Ti K-edge and Ba L 3-edge XANES measurements were performed in a fluorescent mode at ambient temperature. The XANES data revealed that the oxidation state of Ba and Ti ions in all samples was +2 and +4, respectively. Comparing the experimental Cu K-edge XANES spectra to theoretical XANES spectra simulated by FEFF program suggested that the substitution of the Cu ions for B-site ions in BCTZ lattice.

AbstractIn this work, the influence of Yb-incorporated ion on relevant physical, morphological, optical, and also photocatalytic properties of Er-doped bismuth vanadate powders synthesized by the facile sonochemical method was investigated. 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].

AbstractEr3+ doped alkali oxyfluorophosphate glasses were prepared by the melted quenching method and characterized their optical and photoluminescence properties. 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%. All results point out that Er3+ doped alkali oxyfluorophosphate glass could be useful for fiber optic communication material.Keywords: Alkali oxyfluorophosphate glassErbiumfiber optic communication materialMcCumber theory Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe authors would like to thank the National Research Council of Thailand (NRCT) and Thailand Science Research and Innovation (TSRI) for supporting this research.

AbstractLead-free ceramics based on bismuth sodium lanthanum titanate (Bi0.4871Na0.4871La0.0172TiO3: BNLT) and barium titanate (BaTiO3: BT) were prepared by a modified two-step mixed-oxide method. Effects of BT content on the phase transition, thermal expansion behavior, mechanical and electrical properties of lead-free BNLT-BT ceramics were studied. The Burn’s temperature and local polarizations were estimated from the thermal expansion data. Various aspects of understanding the polarization behavior and other effects in this system have also been investigated and discussed. The 0.96BNLT-0.04BT ceramics have shown the d33 value of 135 pC/N. The coercive field (Ec) and remanent polarization (Pr) were found to be 24 kV/cm and 9.0 µC/cm2, respectively.

AbstractIn this research paper, we describe 0.85[0.94Bi0.5Na0.5TiO3-0.06BaTiO3]-0.15[Na0.73Bi0.09NbO3] (BNT-BT-NBN) ceramics fabricated by the solid-state combustion technique. 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. This data indicates that BNT-BT-NBN ceramics can be useful as lead-free materials for high density energy-storage capacitors.Keywords: BNT-BT-NBNphase evolutionRietveld refinementelectrical propertiescombustion method AcknowledgmentsThe authors wish to thank the Department of Physics, Faculty of Science, Naresuan University for their supporting facilities.

AbstractIn this research, (Bi0.487Na0.427K0.06Ba0.026)TiO3 ceramics were prepared by conventional solid-state mixed-oxide method to incorporate Na excess according to the chemical formula (Bi0.487Na0.427+xK0.06Ba0.026)TiO3, where x = 0.0, 0.005, 0.010, 0.015 and 0.020. 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. This research highlights the importance of sufficient control over A-site stoichiometry and how it affects the ferroelectric and piezoelectric properties of BNT-based ceramics.Keywords: Lead-free BNT-BKT-BT ceramicsNa-excessA-site nonstoichiometryFerroelectric propertiesPiezoelectric properties AcknowledgmentsThis work received financial support from the National Science, Research, and Innovation Fund (NSRF) through Naresuan University (Grant No. R2565B059).
