1D–2D composite perovskite films with self-assembled chiral structure for non-reciprocal circularly polarized emission modulation

Abstract

We report a facile wet-treatment strategy to partially transform 2D chiral perovskite films into 1D self-assembled planar chiral structures, resulting in 1D–2D composite films with strong non-reciprocal circularly polarized emission modulation capability, demonstrating potential for advanced optoelectronic applications.
