Cs₂ZnCl₄: a lead-free all-inorganic perovskite with a large dielectric permittivity.

ABSTRACT: 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 Cs₂ZnCl₄. This compound crystallizes in the orthorhombic phase of the Pnma space group, as confirmed by room temperature X-ray diffraction. Through SEM-EDX studies, the morphological distribution and grain size of the Cs₂ZnCl₄ crystal were determined. Optical investigations of our compound in the 200-800 nm wavelength range indicate that the direct band gap has a value of around 3.80 e
