Abstract:
By optimizing interfacial stabilization between quantum dots (QDs) and cholesteric liquid crystals (CLCs), we enhanced the dispersibility of a chiral co-assembly luminophore. In situ photopolymerization yielded highly circularly polarized luminescent films for multimodal anti-counterfeiting. This work links QD surface states to the performance of CLC co-assemblies, advancing applications in polarized displays and security.
