Rewritable Photoluminescence and Structural Color Display for Dual‐Responsive Optical Encryption (Adv. Mater. 14/2024)

Optical Encryption Both wavelength-tunable coloration and light intensity-tunable photoluminescence are independent and reliably manipulated in a rewritable dual-responsive encryption display based on block copolymer self-assembly. The display has the benefit of being a direct and intuitive identification of encrypted information by the human eye, enabling high information security and anti-counterfeiting.
