[CTuP8B-03] Multi-level anti-counterfeiting based on covert structural features embedded in a fs-laser-treated gold/graphene layer
[Presentation Style] Onsite
A gold/graphene hybrid layer works as triple-level anti-counterfeiting after femtosecond laser irradiation. The presence of graphene enables key structural information related to anti-counterfeiting signatures to be covert thoroughly under the surface of the hybrid layer.
