Tunable One-dimensional Photonic Crystals from Soft Materials

Publication date: Available online 5 May 2015 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Youfeng Yue , Jian Ping Gong Photonic crystals are periodic dielectric nanostructures that can affect the propagation of light. Polymer-based photonic crystals have attracted great attentions for their potential application as sensors or optical switches due to their stimuli-responsive properties. This review summarizes the recent developments in one-dimensional (1-D) polymer-based photonic crystals, including the inspiration of the material from nature, principles for design and fabrication, mechanism of color tuning, and their tunable structural color in responsive to various stimuli. A number of fabrication methods, either by bottom-up or top-down approaches for 1-D polymeric photonic crystals have been overviewed. Graphical abstract
