Abstract The glass compositions as ZnO: Li2O: MgO: B2O3 (ZLMB) were synthesized by melt-quenching technique, and studied physical properties such as density and molar volume. The behavior of charged particles such as proton and alpha was examined using the theoretical program by the SRIM coding simulation. The total mass stopping power (TMSP) and projected ranges (PR) were simulated via the SRIM at 0.01 MeV to 10 MeV of the energy ranges. The penetration depth and ion ranges also were simulated. The result found that density increased with increasing ZnO concentrations. In contrast, molar volume decreased when ZnO concentrations increased. However, The TMSP and PR values of proton and alpha particles showed decreased with raising density.

AbstractIn general, NaNbO3 (NN) ceramics are considered to be one of the most promising lead-free perovskites (AFE) materials with low cost, low density, and nontoxic advantages. However, the energy storage capability of this material is often greatly hindered by the hysteresis exhibited during the transition from the antiferroelectric to the ferroelectric phase. In this study, lead-free dielectric (1−x)NaNbO3−xBi(Li1/3Sn2/3)O3, x = 0.0 − 0.08, ceramics were synthesized by solid-state reaction method. The XRD data show a structural change from orthorhombic to pseudo-cubic at x = 0.06 composition. With increasing Bi(Li1/3Sn2/3)O3 content, changes in dielectric properties demonstrated that the AFE P phase was successively replaced by the relaxor AFE R phase, resulting in a thin P–E loop characteristic which leads to the improvement of the energy storage density and efficiency of the ceramic capacitors. The optimum recoverable energy storage density (Wrec = 0.56 J/cm3) and efficiency (η = 74%) were obtained at x = 0.06 under an electric field of 120 kV/cm. The optimum composition also exhibited temperature stability in the range of 25 °C–100 °C. In addition, an increase in Bi(Li1/3Sn2/3)O3 content can lead to a decrease in leakage current density.

AbstractDue to the substitution of complex ions into B-sites is very interesting in recent, lead-free Bi0.47Na0.47Ba0.06Ti1−x(LiNb)xO3 (BNBT1−xLNx) ceramics (with x = 0–0.04) were fabricated by the solid-state combustion method. The influence of (LiNb)4+ (x) on the phase structure, microstructure, and electrical properties was investigated. The X-ray diffraction (XRD) patterns exhibited a pure perovskite structure for all specimens. Coexisting rhombohedral and tetragonal phases were observed in all samples and the tetragonal phase increased with increased x, as analyzed by the Rietveld refinement method. The morphology of the BNBT1−xLNx ceramics, obtained by scanning electron microscopy (SEM), revealed almost-round grain shapes and anisotropic grain growth. The density and average grain sizes decreased from 5.84 to 5.54 g/cm3 and 1.7 to 0.9 µm, respectively, when x increased from 0 to 0.04. The grain size distribution decreased with increased (LiNb)4+ content. A reduction in the dielectric properties was observed, due to the phase ratio changing away from a morphotropic phase boundary (MPB), an inferior microstructure, and low density caused by (LiNb)4+ substitution. The (LiNb)4+ substitution induced the transition from non-ergodic relaxor to ergodic relaxor ferroelectric state.Keywords: BNBT1−xLNxphase formationmicrostructuredielectricferroelectric AcknowledgmentsThe authors thank the Department of Physics, Faculty of Science, Naresuan University for their supporting facilities.

摘要由于近年来络合离子取代b位的研究非常有趣，采用固态燃烧法制备了无铅Bi0.47Na0.47Ba0.06Ti1−x(LiNb)xO3 (BNBT1−xLNx)陶瓷(x = 0-0.04)。研究了(LiNb)4+ (x)对合金相结构、显微组织和电性能的影响。所有样品的x射线衍射(XRD)图均显示为纯钙钛矿结构。通过Rietveld精化法分析，所有样品中均观察到菱形相和四方相共存，并且四方相随x的增加而增加。通过扫描电镜(SEM)观察到BNBT1−xLNx陶瓷的形貌，晶粒形状接近圆形，晶粒生长各向异性。当x从0增加到0.04时，密度和平均晶粒尺寸分别从5.84减小到5.54 g/cm3和1.7减小到0.9µm。随着(LiNb)4+含量的增加，晶粒尺寸分布减小。由于(LiNb)4+取代导致的相比改变、微观结构差和密度低，导致介电性能降低。(LiNb)4+取代诱导了从非遍历弛豫到遍历弛豫铁电态的转变。关键词:BNBT1−xlnx相形成微观结构电性铁电性致谢作者感谢河南大学理学院物理系提供的支持设施。感谢Kyle V.

Abstract The research aims to study the primary interaction between gamma radiation in CeBr3 crystal. The analysis of mass attenuation coefficient (MAC), effective atomic number (Z eff), electron density (N eff), mean free path (MFP), and energy absorption buildup factor (EABF) was evaluated using the using the WinXCom software. Also, the interaction with charged particles as the total mass stopping power (TMSP), projected range (PR) of proton ( ) and alpha ( ) particles were evaluated by SRIM programming. The results found that the MAC depends on the energy ranges, the photoelectric effect is the main interaction at low energy ranges, Compton scattering phenomena illustrate and evidents at intermediate energy ranges, and pair production characteristics dominate over on 1.022 MeV in high energy ranges. Moreover, absorption edges appear on energy’s discontinuity at low energy. The Z eff and N eff show similar trends and correspond to the energy ranges. The MFP of the CeBr3 compared with some standard scintillators such as NaI and BGO crystal and found that the BGO responds to faster interaction than CeBr3 and NaI crystals. The EABF shows scattering energies followed by atomic equivalent (Z eq), and they also increase with increasing penetration depth (mfp). The TMSP and PR depend on charged particles, density, and the unit path distance of a material.

Abstract In this study, the effect of sintering temperature (1000–1100 °C for 2 h) on phase formation, phase transition, microstructure and electrical properties of lead-free piezoelectric (K0.44Na0.52Li0.04)(Nb0.84Ta0.10Sb0.06)O3 (KNLNTS) solid solution with 0.3 wt%Bi2O3 + 0.4 wt%Fe2O3 + 0.2 wt%CuO additive (abbreviate as modified KNLNTS) was investigated. Modified KNLNTS ceramics were synthesized by the solid-state combustion technique using glycine as fuel. The modified KNLNTS powders were prepared using the calcination condition of 650 °C for 2 h. The XRD pattern of all sintered ceramics exhibited a pure perovskite phase. Using Rietveld refinement to analyze the phase formation showed that the modified KNLNTS ceramics had co-existing phases of orthorhombic and tetragonal in all sintered ceramics and the orthorhombic phase increased when the sintering temperature increased. The average grain size, TO-T, Tc, Pr and Ec increased with increasing sintering temperature. At the sintering temperature of 1025 °C, the modified KNLNTS ceramic showed the best electrical properties (Cε ≈ 6745, Smax ≈0.274% and d*33 ≈ 548 pm/V). The good electrical properties of the modified KNLNTS ceramics makes them good candidates for lead-free applications to replace Pb-based ceramics.

Abstract Lead-free Ba1-xLaxTi0.91Sn0.09O3 (BLTS) ceramics with x = 0, 0.01, 0.03 and 0.05, were prepared by the traditional solid-state sintering method with calcination and sintering temperatures of 1200 °C for 2 h and 1400 °C for 4 h, respectively. X-ray diffraction (XRD) measurements revealed that all the BLTS ceramics had pure perovskite structures with no detectable impurities. When x = 0 and 0.01, the ceramics exhibited coexisting orthorhombic (O) and tetragonal (T) phases, while the orthorhombic (O), tetragonal (T) and cubic phase (C) were detected in the BLTS ceramics with x = 0.03 and 0.05, which the Rietveld refinement analysis confirmed. Furthermore, increasing x in the BLTS ceramics led to a large decrease in the average grain size (from 45.7 to 0.9 µm). A significant decrease in the remnant polarization (P r) accompanied by very slim hysteresis loops were observed for higher La (x ≥ 0.03) levels. This demonstrates that BLTS ceramics transition from classical ferroelectric to relaxor ferroelectric behavior due to changing occupancy of the A-site to La3+ from Ba2+.

Abstract HfO2 and La-doped HfO2 with 20, 40, 50, and 60 mol% were deposited on silicon wafers by spin-coating technique. The crystallization process was annealed temperature at 600 °C. Then, characterization techniques of XRD, AFM, SEM, Full-field XRF imaging, and XAS were applied to reveal structural morphology, local structure, grain, distribution, etc. This study aims to investigate the effect of doping La into the HfO2 system on surface formation, microstructure, and dielectric properties. According to the results, RMS surface roughness, and grain size increased relative to La concentration levels. These films demonstrated homogeneous, low surface roughness, and crack-free. The XRD confirms the existence of the monoclinic phase in pure HfO2 and the mixture phase of the monoclinic and orthorhombic phases in La-doped HfO2 films. Increasing La concentration caused the structural transformation, the XAS of La L3 -edge indicating that lanthanum remained in the HfO2 system. Dielectric response based on interface-phase polarization was improved with La content from 0 mol% to 60 mol%. Compared with HfO2 film, the dielectric constant of La-doped HfO2 films was increased and dielectric loss was decreased.

According to the results, RMS surface roughness, and grain size increased relative to La concentration levels. These films demonstrated homogeneous, low surface roughness, and crack-free.

AbstractThe Dy3+ doped lithium sodium potassium borate glasses with white light-emitting were prepared by the melt quenching technique. In this work, optical, photoluminescence properties and Judd-Ofelt analysis of borate glasses have been investigated. For optical properties, Dy3+ doped glasses showed the absorption in visible and near-infrared region, which originate from 6H15/2 ground state to higher state. While the luminescence properties of Dy3+ doped glasses, the emission spectra were presented more intense at 484 nm (blue light) and 574 nm (yellow light) which are essential for white light emitting materials, whilst decay time decrease with an increase of Dy2O3 contents. The emission intensity of Dy3+ doped glasses were enhanced by adding Dy2O3 concentrations until 0.5 mol%, after that the emission intensities were decreased due to the concentration quenching effect. Judd-Ofelt is analyzed by using the absorption and photoluminescence results, The stimulated emission cross-section has been investigated in this work. The CIE 1931 chromaticity investigation shows that Dy3+ doped glass emitted light with white color. Hence, these glasses may be suitable candidates for use in W-LEDs material.Keywords: Alkali borate glassdysprosiumJudd-Ofeltwhite light emission AcknowledgmentsT.S. would like to acknowledge supports from Faculty of Science and Technology, Rajamangala University of Technology Phra Nakhon (RMUTP) and Thailand Science Research and Innovation (TSRI).

AbstractThe rapid economic growth in recent years has led to the use of glass material in many activities, resulting in a large amount of glass waste. The efficient use of waste glass recycling has gained increasing attention. Researchers propose a method for recycling waste glass to reduce glass manufacturing costs and investigate the physical, optical, and luminescence properties of chromium oxide-doped glass with the stoichiometry of (35-x) B2O3: 35SiO2 (use waste glass as SiO2): 12Na2O: 7.9CaO: 0.1Sb2O3: 10BaO: xCr2O3 when x = 0.00 to 0.05 mol%. Glass was synthesized using the melt quenching at 1,200 degrees Celsius for 3 h. Archimedes’ principle and the Abbe refractometer were used to calculating density and refractive index decrease with the addition of 0.01 mol% of Cr3+ concentration. At room temperature, absorption spectra were analyzed using a UV-VIS-NIR spectrometer exhibiting two broadband at 438 and 625 nm intense bands, and the luminescence properties of the Cr3+ glasses system were investigated using an excitation wavelength of 567 nm, with luminescence peaks observed around 750 nm. CIE L* a* b* shows the green color.Keywords: Recycled waste glasschromium oxidephysical propertiesoptical propertiesluminescence properties Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe authors would like to thank under the project number N41A640252 This research project is supported by National Research Council of Thailand (NRCT), Thailand Science Research and Innovation (TSRI), The authors would like to thank the centre of Excellence in Glass Technology and Materials Science (CEGM), NPRU and Gemories Thailand Co., Ltd for providing the facilities.
