摘要
Chirality induction in organic-inorganic halide perovskite nanocrystals has attracted substantial attention, yet producing circularly polarized luminescence without high magnetic fields or cryogenic settings remains an exacting task. By incorporating a chiral spacer into the crystal lattice and another chiral ligand on the crystal surface, Liu et al. report a polarization degree of 5.2% in mixed-phase perovskite nanocrystals arising from enhanced asymmetric light absorption and delayed spin-flip of photogenerated charge carriers. This work paves the way toward in situ asymmetric photochemical reactions using chiral perovskite nanoscintillators.
