Chirality is an important property for inducing spin-selective responses in optical information processing and opto-spintronics. However, the handedness of circularly polarized luminescence (CPL) from a single chiral material is generally fixed by its intrinsic structure. In this study, we demonstrate handedness inversion of CPL in a microcavity containing chiral two-dimensional perovskites, without structural modification or the application of an external magnetic field. This inversion is achieved by tuning the cavity length, which modulates the exciton–photon hybridization ratio.
