Item type:Publication, Synthesis and characterization of CH3NH3PbI3 and CH3NH3PbI(3-x)Clx perovskite solar cell materials(2019-11-18); Kidkhunthod, PinitThe emerging of perovskite solar cell has attracted many interests in the synthesis and characterization of hybrid perovskite materials related to methylammonium iodide (MAI) due to various promising properties. In this work, we found a faster way to synthesize hybrid perovskite CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf> and CH<inf>3</inf>NH<inf>3</inf>PbI<inf>(3-x)</inf>Cl<inf>x</inf> (x = 0,1,2) powders from a different solvent in the preparation process of MAI precursor. In addition, it was found that in CH<inf>3</inf>NH<inf>3</inf>PbI<inf>(3-x)</inf>Cl<inf>x</inf> powders, as characterized by XRD and XAS, with a solid-state method employed Cl atoms cannot directly substitute for I in the perovskite (ABX<inf>3</inf>) structure. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Influence of Pb(In1/2Nb1/2)O3 on the phase transitions, electrical, and thermal properties of a PbZrO3 ceramic(2011-10-01); ; ; The solid solution of a (1-x)PbZrO<inf>3</inf>-xPb(In<inf>1/2</inf>Nb <inf>1/2</inf>)O<inf>3</inf> (PZ-PIN) system, with x=0.00-0.50, was synthesized using the wolframite precursor method. The effects of the PIN content on the crystal structure, and the electrical and thermal properties of a PbZrO <inf>3</inf> ceramic were investigated using X-ray diffraction, dielectric spectroscopy, hysteresis measurement, and differential scanning calorimetry techniques. Furthermore, the morphology and grain size were determined using scanning electron microscopy. The results indicated that the pure perovskite phase was obtained for all compositions, and the solid solution, PZ-PIN, changed from orthorhombic to rhombohedral symmetry when the amount of PIN increased. A ferroelectric intermediate phase began to appear between the paraelectric and the antiferroelectric phases of pure PZ, with increasing PIN content. The temperature range width of the ferroelectric phase also increased continuously with increasing PIN. At room temperature, the polymorphic phase transition (PPT) was identified from the orthorhombic to the rhombohedral phase in (1-x)PZ-xPIN at the composition, x=0.40. The ceramics (x=0.40) with PPT close to room temperature exhibited excellent electrical properties (ε<inf>rmax</inf>= 33240 and P<inf>r</inf>=26.94 μC/cm<sup>2</sup>). © 2011 The American Ceramic Society. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effect of Pb(Y1/2Nb1/2)O3 additions on thermal and electrical properties of PbZrO3 ceramics(2011-07-29); ; ; The solid solution of a (1-x)PbZrO<inf>3</inf> - xPb(Y<inf>1/2</inf>Nb <inf>1/2</inf>)O<inf>3</inf> (PZ - PYN) system, with x = 0.00 - 0.08, was synthesized by the wolframite precursor method. The effects of PYN content on crystal structure, and electrical and thermal properties of PbZrO<inf>3</inf> ceramic were investigated. The crystal structure of sintered ceramics was characterized by X-ray diffraction. The pure perovskite phase was obtained for all compositions. The transition temperatures of the AFE to PE phase become lower with PYN increase. The dielectric properties of PZ were improved by the addition of PYN.

Item type:Publication, Dielectric, ferroelectric and piezoelectric properties of the lead free 0.9BaTiO3-(0.1- x)Bi0.5Na0.5TiO3- x Bi(Mg0.5Ti0.5)O3 solid solution(2016-01-02); ; Solid solution of 0.9BaTiO<inf>3</inf>-(0.1-x)Bi<inf>0.5</inf>Na<inf>0.5</inf>TiO<inf>3</inf>-xBi(Mg<inf>0.5</inf>Ti<inf>0.5</inf>)O<inf>3</inf> (BT-BNT-xBMT) system, where x = 0.00, 0.02, 0.04, 0.06, 0.08, 0.10, was synthesized by the solid state reaction. Dense BT-BNT-xBMT ceramics were obtained by sintering at 1,150-1,250C for 4 h. The effect of BMT on crystal structure and electrical property of BT-BNT ceramics was investigated as a function of composition, x, using X-ray diffraction, dielectric spectroscopy, hysteresis and strain measurements. The crystal structure of solid solution BT-BNT-xBMT, where x = 0.00-0.10, successively transforms from tetragonal to pseudocubic symmetry, with increased BMT concentration. Temperature dependence of dielectric constant (ε<inf>r</inf>) and dielectric loss (tanδ) for BT-BNT-xBMT at various frequencies showed that phase transition of ceramics changed from ferroelectric to relaxor-like behavior as BMT content increased. Furthermore, remanent polarization (P<inf>r</inf>), coercive field (E<inf>c</inf>) and the normalized strain (d<inf>33</inf>∗) of BT-BNT-xBMT ceramics tend to decrease with increasing BMT concentration. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effect of Pb (Yb 1/2Nb 1/2)O 3 on phase transition and thermal and electrical properties of PZ-PYbN solid solution on PZ-rich side(2012-02-01); ; ; The (1 - x)PbZrO <inf>3</inf>-xPb(Yb <inf>1/2</inf>Nb <inf>1/2</inf>)O <inf>3</inf> (PZ-PYbN) ceramics, with the compositions, x = 0.00-0.50, were prepared by the wolframite precursor method. The crystal structure and electrical and thermal properties of PbZrO <inf>3</inf> ceramic were investigated as a function of the composition, x, using X-ray diffraction, dielectric spectroscopy, hysteresis measurement and differential scanning calorimetry techniques. The results indicated that the solid solution, PZ-PYbN, changed from orthorhombic to rhombohedral symmetry when the amount of PYbN increased. The pyrochlore phase identified as Yb/Nb mixed compound was observed at the composition, x ≥ 0.2. For the compositions, x = 0.00-0.10, ceramics showed a sharp phase transition from AFE to PE. Furthermore, the intermediate FE phase was absent from the PZ-PYbN system. © 2011 Springer Science+Business Media, LLC.
