Optical anti-counterfeiting technology, as a preventive measure, has deeply permeated our daily lives. Visually readable codes designed based on optical materials are widely used due to their ease of verification, reasonable cost, and difficulty in replication. The rapid development of modern technology and the increasingly rampant activities of counterfeiting pose greater challenges to optical anti-counterfeiting technology. Consequently, optical anti-counterfeiting material systems based on multimodal integrated applications have garnered widespread attention.
