Metal halide perovskites show promise for lighting applications, but their multiexcitonic emission processes are not fully understood. This study delves into the in metal to enhance our understanding of optical properties and potential technologies. Specifically, this focuses on Bi3+ doped Cs2ZrCl6 lead-free perovskite crystals, showcasing optoelectronic applications. The crystals were synthesized using a solvothermal method with varying concentrations. X-ray diffraction (XRD) analysis showed structural parameters perovskite. material had truncated octahedron morphology, as confirmed by scanning electron microscopy (SEM).
