Crystal structure, bandgap, photoluminescence and resistivity properties of double perovskite Cs₂AgBiCl₆ single crystal and its thin film.

ABSTRACT: Lead-free Cs₂AgBiCl₆ double perovskite (Cs₂AgBiCl₆-DP) material, as a substitute for lead halide perovskite materials, has the advantages of environmental friendliness and high stability and has attracted much attention. However, the photoluminescence and conductive properties of Cs₂AgBiCl₆-DP have not been well studied. In this study, we prepared Cs₂AgBiCl₆-DP single crystals (SCs) by coordination-dissolution and coordination-precipitation method. Single- and powder-XRD, SEM, EDS, XPS, and EPR characterization were performed to confirm the structural characteristics of Cs₂AgBiCl₆-DP SCs. The Tauc diagram based on UV-visible (UV-vis) absorption spectroscopy reveals that the optical
