Abstract

Photonic crystals based anti-counterfeiting materials have recently attracted great interests due to their unique optical properties and great market demand. As an essential step to prepare these antifraud materials, the creation of color contrast and thereby photonic crystal patterns based on ink-jet printing on flat substrate or localized tuning of premade photonic structures will be first introduced in this chapter. The antifraud labels could be photonic prints with angular dependent structural colors, since they are easy to be distinguished from most regular prints. They could also be invisible photonic prints under normal conditions, until special treatments such as water soakage, deformation and magnetic field are applied to reveal the hidden patterns. Finally, the photonic crystal multilayer has proved its potential in encryption applications, where the encrypted information of stacking sequence can be interpreted by the corresponding reflection spectra only.
