Chiral　perovskites　are　considered　as　promising　candidates　for　circularly　polarized　luminescence　(CPL)　light　source,　by　attracting　the　broader　scientific　community　for　their　applications　in　chiral　optoelectronics　and　spintronics.　However,　it　is　still　a　great　challenge　to　achieve　both　substantial　photoluminescence　asymmetry　(gCPL)　and　high　photoluminescence　quantum　yield　(PLQY)　simultaneously　for　high　CPL　brightness　due　to　the　limitations　associated　with　magnetic　transition　dipole　moments.　Herein,　this　problem　is　overcome　and　achieve　both　large　gCPL　of　1.6×10−2　and　PLQY　of　56%　in　chiral　perovskite　through　the　magnetic　element　doping　strategy.　The　substitution　of　Pb2+　ion　with　smaller　magnetic　Mn2+　ions　shrinks　the　crystal　lattice　around　[MnBr6]4−　octahedra,　amplifying　the　asymmetric　distortion　surrounding　the　Mn2+　ions.　Moreover,　the　transition　associated　with　Mn2+　ions　can　harvest　the　photoexcitation　energy　in　chiral　perovskites,　and　its　spin-flipping　characteristics　enable　highly　efficient　CPL　from　the　d–d　transition　on　Mn2+　energy　levels.　Furthermore,　this　magnetic　element　doping　strategy　is　proven　to　be　a　universal　tactic　for　enhancing　CPL　brightness　as　confirmed　in　a　series　of　1D-　or　2D-chiral　perovskites　with　various　chiral　ligands　or　halogens.　The　findings　provide　an　in-depth　understanding　of　the　structure-property　relationship　in　chiral　perovskites　toward　chiral　optoelectronic　and　spintronic　applications.　©　2024　Wiley-VCH　GmbH.
