Abstract
The pursuit of chiral lead-free metal halides with both high photoluminescence quantum yield (PLQY) and large luminescence dissymmetry factor (glum) remains a priority for designing efficient circularly polarized light sources. However, a tradeoff exists between PLQY and glum in chiral materials due to the mismatched electric (μ) and magnetic transition dipole moment (m). Herein, we address this contradiction and develop the efficient circularly polarized luminescence (CPL) emitters through structural dimension modulation. By tuning the size and polarization of chiral organic cations and employing the cascade cationic insertion strategy, 0D, 1D and 3D indium-based chiral metal halides are constructed. These…
