Solution-processed structural colors and their applications
Abstract
A comprehensive review of solution-based fabrication methods for structural colors. Covers 3DOM (three-dimensionally ordered macroporous) synthesis techniques including sol-gel chemistry, polymerization, salt-precipitation and chemical conversion. The review demonstrates that bottom-up self-assembly strategies provide low-cost, scalable routes to photonic nanostructures.
