Chiral defect-induced blue photoluminescence and circularly polarized luminescence of zero-dimensional Cs 4 PbBr 6 perovskite nanocrystals

Chiral-defect-induced strategy is employed to synthesize zero-dimensional chiral Cs 4 PbBr 6 perovskite nanocrystals (NCs) with blue photoluminescence and CPL response via a phase transition process.
