Fundamentals, Advances, and Artifacts in Circularly Polarized Luminescence (CPL) Spectroscopy (Adv. Mater. 44/2023)

Circularly Polarized Luminescence Circularly polarized luminescence (CPL) is the emission of left- or right-handed helical light, and a key property of certain chiral materials with applications such as highly efficient displays, holography, sensing, enantiospecific discrimination, synthesis of drugs, quantum computing, and cryptography. In article number 2302279 by Sascha Feldmann and co-workers, the fundamentals, advances, pitfalls and software for accurately measuring CPL are described.
