Fast a‐site cation cross‐exchange at room temperature: single‐to double‐ and triple‐cation halide perovskite nanocrystals

HIGHLIGHTS

• who: Angewandte et al. from the (UNIVERSITY) have published the paper: Fast Au2010Site Cation Crossu2010Exchange at Room Temperature: Singleu2010to Doubleu2010 and Tripleu2010Cation Halide Perovskite Nanocrystals, in the Journal: (JOURNAL)
• what: The authors report here fast A-site cross-exchange between APbX3 (NCs) made of different A-cations (Cs (cesium) FA (formamidinium) and MA (methylammonium)) at room temperature.
• how: Different volumes of the as-synthesized colloidal dispersion of FAPbI3 NC were added to a freshly prepared CsPbI3 NC dispersion at room temperature to obtain CsxFA1 xPbI3 NCs with different Cs/FA ratios (similar results . . .
