Lead-Free Cs₂AgBiCl₆ Double Perovskite: Experimental and Theoretical Insights into the Self-Trapping for Optoelectronic Applications.

ABSTRACT: Lead-free double perovskites (DPs) will emerge as viable and environmentally safe substitutes for Pb-halide perovskites, demonstrating stability and nontoxicity if their optoelectronic property is greatly improved. Doping has been experimentally validated as a powerful tool for enhancing optoelectronic properties and concurrently reducing the defect state density in DP materials. Fundamental understanding of the optical properties of DPs, particularly the self-trapped exciton (STEs) dynamics, plays a critical role in a range of optoelectronic applications. Our study investigates how Fe doping influences the structural and optical properties of Cs₂AgBiCl₆ DPs by understanding their STEs dynamics, which is currently lacking in the literature.
