Summary: Introducing chirality into metal-halide hybrids has led to various emerging properties such as chiroptical activity, spin-dependent transport, and ferroelectricity. However, most chiral metal-halide hybrids are non-emissive, and the mechanism behind this is not well understood. In this study, we present a new strategy to activate circularly polarized luminescence (CPL) in chiral metal-halide hybrids by alloying Sb3+ into chiral indium-chloride hybrids. This results in highly luminescent chiral indium-antimony chlorides with strong CPL signals and tunable energy.

Summary: Metal halide perovskites, especially the layered two-dimensional materials, have attracted extensive attention due to their excellent optoelectronic properties. In this study, a 2D Ruddlesden-Popper phase Cs3Cd2Cl7 was synthesized by a solvothermal method, and the photoluminescence quantum yields (PLQYs) were significantly enhanced through appropriate Sb doping. The highly efficient cyan emission can be attributed to the self-trapped exciton (STE) emission induced by strong electron-phonon coupling, and Sb-doped Cs3Cd2Cl7 exhibits excellent structural and spectral stability.

Summary: The relationship between structural asymmetry and optoelectronic properties of functional materials is an active research field. The chiral-induced spin selectivity (CISS) effect controls spin populations without magnetic components and has been mainly studied in chiral organic molecules and their assemblies. Introducing chirality into semiconductors, such as chiral metal halide semiconductors (MHSs), allows for control over charge, spin, and light without magnetic components, leading to breakthroughs in our understanding of CISS and spin-dependent optoelectronic properties.
