Mechanically robust cellulose nanocrystal photonic films with propagation-switchable circularly polarized room-temperature phosphorescence.
The development of circularly polarized room-temperature phosphorescence (CPRTP) materials that simultaneously combine tunable photonic properties, long-lived emission, and mechanical robustness remains challenging. Here, we fabricate a series of poly(vinyl alcohol) (PVA)-reinforced cellulose nanocrystal (CNC) chiral p...
