Circularly polarized luminescence: materials, photophysics, devices, and applications
摘要
The research on circularly polarized luminescence (CPL) has received significant attention due to its promising applications in advanced optical technologies. This review summarizes the latest advancements in the development of CPL-active materials across organic, hybrid, and inorganic systems. Particular emphasis is placed on material design strategies that simultaneously achieve high luminescence efficiency and large dissymmetry factors (glum) through chiral induction, molecular engineering, and supramolecular organization. The review further explores the cutting-edge applications of these CPL materials in optoelectronic devices, as well as emerging uses in information encryption, anti-counterfeiting, and chiral sensing. Finally, the review highlights current challenges and future prospects in the field, addressing fundamental limitations in material performance, device integration, and scalability. This review aims to provide valuable insights and inspire future research that will advance CPL technologies toward practical implementation in photonics and optoelectronics.
