Herein, we optimized the colloidal synthesis of undoped and Bi-doped Cs<sub>2<\/sub>AgInCl<sub>6<\/sub>&nbsp;nanocrystals (NCs) via the facile hot-injection process using nontoxic and available precursors. The synthesis conditions including temperature, ligands, and hydrochloric acid are investigated to boost the photoluminescence quantum yield (PLQY) of Cs<sub>2<\/sub>AgInCl<sub>6<\/sub>:Bi NCs with the trace amount of Bi doping. The broad-band orange emission peaking at 580 nm is observed with the PLQY as high as \u223c11.4%, and the related luminescence mechanism has been discussed. This work provides a reliable avenue toward the optimization of optical properties for emerging lead-free halide perovskite NCs with enhanced PLQY.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Chem.
