Carbon dots (CDs) with circularly polarized afterglow (CPA) materials have drawn increasing attention as cutting-edge research in the field of chiral luminescence owing to their promising applications various fields. However, due weak optical activity CDs and limited color phosphorescent CDs, it is still a formidable challenge construct multicolor CD-based CPA high dissymmetry factor (glum). Herein, positively charged aggregation-induced emission (AIE) were prepared using dithiosalicylic acid ionic liquid precursors. Encapsulating AIE nematic structure negatively cellulose nanocrystal (CNC) films enabled production surprising warm white glum up −0.16. To further expand afterglow, phosphorescence resonance energy transfer between commercial fluorescent dyes was constructed CNC films. Finally, potential advanced dynamic information encryption explored by virtue different lifetimes.

Multicolor luminescent materials hold great potential in high-level optical anticounterfeiting and encryption technologies. However, achieving multiple luminescence a single phosphor with dopant, especially covering visible invisible regions simultaneously, remains standing challenge. Herein, we successfully realize dual-band emission single-doped γ-AlON:Mn2+ phosphors. Under 450 nm light excitation, the low-doped γ-AlON:xMn2+ phosphors (x ≤ 0.02) emit narrowband green at 515 nm; however, when further increasing Mn2+ concentration, heavy-doped ≥ 0.05) samples display an additional broad near-infrared band peaking 730 nm. Such intriguing spanning from to regimes is assigned combined emissions of isolated tetrahedral ions superexchange-coupled Mn2+-Mn2+ pairs γ-AlON host. Exploiting distinct photoluminescence low- high-doped phosphors, double-level information demonstration. This work first presents dual-emission not only enabling but also shedding on tuning inorganic
