摘要

Artificial chiralstructural- color materials can carry high- dimensional information on multiple optical degrees of freedom, providing possibilities for advanced optical rity and information storage. However, current artificial chiralstructural- color materials are hindered by their specific compositions, fine nanostructures, and single polarization modulation. Here, we found that microdomes made from common polymers have structural colors with broadband tunability and multiple polarization- modulated ity. The microdome patterns are easily fabricated by ordinary printing techniques have inhomogeneous spatial distributions of full polarization states and customizable colors. Our chiralstructural- color microdomes (CSCMs) provide a promising roadmap for high- capacity information encryption and high- security anti- counterfeiting. developed multidimensional tunable structural color displays and achieved encryption with high information capacity. To further highlight the application potential, we structed contact lenses integrated with CSCMs for identity authentication with distinctive cryptograms.
