Circularly Polarized Light Emission From Single Chiral Hedgehog Particles Coated with Nanofilms of Achiral Perovskites.

ABSTRACT: Metal-halide perovskites are known for their strong and tunable luminescence. However, the synthesis of perovskite-based particles with circularly polarized light emission (CPLE) remains challenging due to the complex interplay of metal-ligand chemistries, crystallization patterns, and chirality transfer mechanisms. Achiral perovskites can be deposited on chiral "hedgehog" particles (CHIPs) with twisted spikes, producing chiroptically active materials with spectroscopic bands specific to the perovskite and chirality specific to the template CHIPs. Left- and right-handed CPLE is engineered into complex particles comprised of a layer of perovskite deposited onto CHIPs coated with an intermediate silica layer. The spectral position of chiroptical bands, the optical asymmetry g-factors, and si
