Chiral defect-induced blue photoluminescence and circularly polarized luminescence of zero-dimensional Cs₄PbBr₆ perovskite nanocrystals

Abstract

Chiral-defect-induced strategy is employed to synthesize zero-dimensional chiral Cs4PbBr6 perovskite nanocrystals (NCs) with blue photoluminescence and CPL response via a phase transition process.
