Triple‐State Invisible Photonic Crystal Pattern Encrypted in Hollow‐Silica/Polyurethane Film for Anticounterfeiting Applications

An invisible photonic crystal (PC) pattern encrypted at the dry state and decrypted by solvent is a new anticounterfeiting material system, but its diversity and complexity in response are still required to be increased to enhance the anticounterfeiting effect.Herein, a triple?state invisible pattern encrypted in hollow?silica/polyurethane (h?SiO2/
