Mechanically robust cellulose nanocrystal photonic films with propagation-switchable circularly polarized room-temperature phosphorescence
Zhenduo Qiu, Xiaoqing Liu, Xiaoxiao Yu, Xinhai Zhang, Yanhua Cheng, Meifang ZhuPVA-reinforced CNC chiral photonic films were fabricated by helicoidal self-assembly and PVA infiltration, enabling tunable photonic bandgaps/structural colors, room-temperature phosphorescence, and excitation-direction-dependent CPL switching.
