CsZnCl: a lead-free all-inorganic perovskite with a large dielectric permittivity.

In recent years, inorganic perovskite materials based on metallic halides have attracted significant attention due to their non-toxicity and ease of synthesis, making them suitable for various applications. This article describes the slow evaporation approach at room temperature for the fabrication of a non-toxic inorganic perovskite based on metallic halide CsZnCl. This compound crystallizes in the orthorhombic phase of the space group, as confirmed by room temperature X-ray diffraction.

Structural, dielectric and transport properties of NaFeMnO ( = 1 and 2/3).

NaFeMnO ( = 1 and 2/3) layered oxides were prepared by an improved solid-state synthesis method. The XRD analysis confirmed the high purity of these samples. The Rietveld refinement of the crystalline structure illustrated that the prepared materials crystallize in a hexagonal system in the space group with the P3 structure for = 1 and in a rhombohedral system with the 6/ space group and P2 structure type for = 2/3.

Structural, optical, electric and dielectric characterization of a NaCuFeMnO compound.

The compound NaCuFeMnO was synthesized using a solid-state method and it crystallized in a hexagonal system with a 3̄ space group in an O3-type phase. The optical properties were measured using UV-Vis absorption spectrometry to determine the absorption coefficient and the optical band gap . The optical band gap energy of this sample is 2.

The dielectric relaxation behavior induced by sodium migration in the NaCoSiO structure within a three-dimensional Co-O-Si framework.

The disodium cobalt(ii) orthosilicate material (NCS) has been synthesized using improved solid-state (NCS-SS) and co-precipitation (NCS-CP) methods of synthesis. The Rietveld refinement of the XRD pattern of NaCoSiO has demonstrated an orthorhombic crystal system with the space groups 2 and for NCS-SS and NCS-CP respectively. The elemental mapping of microstructures by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) showed the porous morphology and the homogenous particles of the NaCoSiO powders.

Electrical and electrochemical properties of LiM(WO) (M = Ni, Co and Cu) compounds.

LiM(WO) (M = Co, Cu or Ni) materials have been synthesized using the solid-state reaction method. X-ray diffraction measurements confirmed the single phase of the synthesized compounds in the triclinic crystal system (space group 1̄). The SEM analyses revealed nearly spherical morphology with the particle size in the range of 1-10 μm.
