Self-trapped excitons (STEs) in metal halide materials are attracting an increasing level of interest due to their unique light emission properties. Light from STEs halides is usually associated with excited-state structural deformation, which lowers the symmetry local structures, as seen for a wide range systems. Here, we reveal prototypic STE-associated "distortion" that, however, enhances series all-inorganic copper(I)-based Cs3Cu2X5 (X = Cl, Br, or I). We further find that peaks...
The structure and thermoelectric (TE) properties of La-doped, A-site-deficient SrTiO3 (Sr1–3x/2LaxTiO3) ceramics sintered in air N2/5% H2 have been investigated. Air-sintered with 0.10 ≤ x < 0.30 appear cubic by X-ray diffraction (XRD) but exhibit superstructure consistent a tetragonal cell (a0a0c–), according to electron (ED) studies. 0.50 additional short-range A-site vacancy (VA) ordering, ≥ are orthorhombic an a–a–c+ tilt system long-range VA ordering. reduced oxygen-deficient XRD...

Abstract Ba 1+1/ M [Si 2 O 5+1/ ] low‐permittivity microwave dielectric ceramics are prepared using the conventional solid‐state method. Pure phases obtained in barium silicates with = 1, 3, 4, 5, and ∞, except for 7, which two phases, 5 Si 8 21 BaSi , observed. As complexity of crystal structure described by Shannon information per reduced unit cell increases, τ f value tends to change from a negative positive value, has highest complexity. A single phase ε r anomaly peak at −180°C exhibits...
The ion valence state, phase composition, microstructure, and microwave dielectric properties of Sr (1−1.5 x ) Ce TiO 3 ( = 0.1–0.67, SCT) ceramics were systematically investigated. produced with gradual structural evolution from a cubic to tetragonal turned an orthorhombic structure in the range 0.1 ≤ 0.67. Above critical proportion 0.4), microstructural changes normal grain growth initially occurred. On basis chemical analysis results, reduction Ti 4+ ions was hastened by tetravalent (Ce...
Perovskite oxides have been recognized as one of the most attractive oxygen evolution reaction (OER) catalysts because their low cost, earth abundance, and robust nature. Herein, one-dimensional porous LaFe1-xNixO3 (LFNO) perovskite oxide nanofibers (LFNO NFs) are fabricated with a feasible electrospinning route its further post-calcination treatment. By tailoring atomic percent Fe Ni in oxide, we determined that LaFe0.25Ni0.75O3 (LFNO-III) NFs afford best OER activity among all prepared...
(1− x )ZnAl 2 O 4 − Mg TiO microwave dielectric ceramics were synthesized using the solid‐state reaction. The variation of microstructures, phase compositions, and properties with amount have been investigated. It can be observed from XRD results that a single‐phase solid solution is formed in ( =0.1) ceramics, however, increase value, second‐phase MgTi 5 MgTiO 3 appear between range 0.21≤ ≤0.8 0.9≤ ≤1.0, respectively. As increases, ɛ r value increases almost linearly 9.1 to 14.1, Q × f...
