Research and Application Progress of Photonic Crystals
By introducing stimulus-responsive materials or constructing porous structures within photonic crystals,structural colors with responsive color-changing properties could be created.Based on the exploration of the characteristics of photonic crystal structural color in recent years,the study of their applications in coloring,anti-counterfeiting,relative humidity monitoring,temperature sensing,VOCs detection,pH and stress monitoring were elaborated.The future application prospects of photonic crystal structural color materi-als across diverse fields were also anticipated.
