Abstract

Abstract : The study of chiral photoluminescence in colloidal metal nanostructures extends photoluminescence research to the chiral realm and can enable a deep understanding of optical chirality. In article number 2101502, Dangyuan Lei and co‐workers report the chiral excitation and emission properties of single gold nanohelicoids (GNHs) with intrinsic structural chirality. Single GNHs exhibit polarization‐steered chiral photoluminescence under circular polarized excitation, and attribute this observation to the chiral Purcell effect.
