Summary
Stimulus-responsive nonclose-packed photonic crystals (NPCs) mimic natural structural colors. This review details NPC fabrication, mechanisms, and applications in sensors and displays.
Area of Science:
- Materials Science
- Nanotechnology
- Optics
Background:
- Stimulus-responsive photonic crystals (PCs) with nonclose-packed structures are gaining attention for mimicking natural structural colors.
- Existing literature lacks a systematic review on nonclose-packed photonic crystals (NPCs).
Purpose of the Study:
- To provide a comprehensive review of the progress in nonclose-packed photonic crystals (NPCs).
- To summarize fabrication, working mechanisms, and applications of NPCs.
Main Methods:
- Reviewing fundamental principles and fabrication strategies for 1D, 2D, and 3D NPCs.
- Categorizing responsive NPCs based on stimuli (physical, chemical, biological).
- Discussing applications in sensors, printing, anticounterfeiting, displays, and optical devices.
Main Results:
- Detailed summary of NPC design principles, focusing on nonclose-packed structures.
- Classification of NPCs based on responses to diverse physical, chemical, and biological stimuli.
- Overview of current and potential applications of NPCs.
Conclusions:
- This review establishes design principles for NPCs.
- It provides a foundation for developing next-generation responsive photonic crystals.
