Back Cover: High-yield upcycling of feather wastes into solid-state ultra-long phosphorescence carbon dots for advanced anticounterfeiting and information encryption (EXP2 6/2024)
This work presents a high-yield approach to recycle duck feather into carbon dots (CDs) via hydrothermal treatment. The resultant CDs exhibit matrix-free solid-state fluorescence under ultraviolet lamp, and long-lived green room-temperature phosphorescence after removing ultraviolet lamp. Furthermore, their ink demonstrates excellent potential in anticounterfeiting and information encryption, offering a distinctive perspective to reclamation of the feather wastes for environmental sustainability.
