Tuning Crystal Growth of Colloidal Cs₃Bi₂I₉ Perovskite-Like Nanocrystals via a Solvent-Assisted Reprecipitation Approach.

ABSTRACT: Lead-free bismuth-based perovskite-like materials have emerged as promising alternatives to lead halide perovskites due to their enhanced stability and lower toxicity. Colloidal approaches for the synthesis of such materials offer the advantage of morphology engineering and precise control over size and shape. However, conventional approaches require long-chain organic ligands, which hinder charge transport and limit their applicability in optoelectronic devices. Herein, a ligand-free Solvent-Assisted Reprecipitation (SARP) approach is introduced, exploiting solvent-mediated synthesis to control the nucleation and growth of Cs₃Bi₂I₉ nanocrystals. The use of solvent descriptors, such as Kamlet-Taft parameters, enables preliminary screening of suitable solven
