摘要

Abstract

The development of multi-mode and multi-level optical anti-counterfeiting systems holds tremendous significance for advanced information encryption and modern security. Herein

we developed a high-level information encryption platform based on a stimuli-responsive perovskite/polydiacetylene (PDA)/poly(vinyl alcohol) (PVA) composite hybrid film. By strategically integrating luminescent perovskite nanocrystals onto a twisted-stacking uniaxially oriented PDA/PVA heterostructure

three distinct optical dimensions

including pattern morphology

bright photoluminescence

and high-performance circularly polarized luminescence (CPL

with

lum

up to 1.0)

were successfully coupled into a single flexible platform. Crucially

the three diverse optical channels can be operated independently without mutual interference. By leveraging the fast halogen anion exchange of the perovskite layer and the thermochromic phase transition of the PDA layer as orthogonal cryptographic keys

precise and reversible modulation of each optical mode was achieved. This dual-stimulus response mechanism enables a dynamic

multistage decryption profile that successfully transitions from a predefined camouflage state to authentic target information. This programmable and flexible hybrid film provides an innovative crosstalk-free paradigm for next-generation anti-counterfeiting and hierarchical information encryption.
