Atomistic Insights into Halide Double Perovskite Nanocrystals obtained by Multistep Synthesis and Efficient Compositional Engineering.

ABSTRACT: Lead-free halide double perovskites (HDP), particularly those within the Cs₂B⁺InCl₆ family that show a direct band gap, have recently emerged as promising semiconductors to address key challenges associated with lead-based perovskites, such as toxicity and instability in air and moisture. Their compositional flexibility, structural versatility, and ease of cation transmutation offer considerable potential for bandgap engineering. Here, we present a versatile, multistep, solution-based synthetic strategy for HDP nanocrystals. This method separates the precursor dissolution and reaction stages, providing much greater control over the synthesis. The flexibility of this approach makes it widely generalizable and highly adaptable to high-throughput flow chemistr
