Defect-Induced Circularly Polarized Luminescence of Chiral Perovskite Films

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

“…11 In addition, our previous work found that defects in chiral perovskites can induce strong photoluminescence and exhibit a strong CPL response. 23 This result indicates that defects in chiral perovskites can give rise to strong photoluminescence and CPL because the chiral defects improve the recombination rate of the exciton. Thus, can CPL be realized by creating chiral defects in achiral perovskites?…”
