Chirality Induction at Helically Twisted Surface of Nanoparticles Generating Circularly Polarized Luminescence

International audienceCircularly polarized luminescence (CPL) can be generated either from fluorescent dyes with chiral structures or from achiral luminophores in chiral environments such as chiral hosts or chiral self-assemblies. Herein, we demonstrate the CPL induction to an achiral fluorophore grafted on an inorganic nanoparticle (NP) with a chiral shape. Nanoparticle
