Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids
Advanced Functional Materials, EarlyView.Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.
