“…structural color); d hkl is the crystal plane spacing of the hkl plane (related to the particle diameter of particles); n avg is the average refractive index of the microsphere in a specific environment; h is the observation angle; m is Bragg diffraction order. According to the Bragg diffraction equation ( 1), 53 PC structural color is related to refractive index, particle diameter, observation angle, and other factors of colloidal particles. From Figure 2, on the premise that other factors remain unchanged, the particle diameter of colloidal particles increases and wavelength increases accordingly, indicating that the PBG moves to the long-wave direction, that is, the structure color of PC has a red shift.…”

Photonic crystals have attracted extensive attention because of their wide application in optics and photonics. These structures can be made by “top-down” or “bottom-up” self-assembly methods. Self-assembly methods have received particular attention due to their low cost, simple manufacturing process, relatively easy scaling, and ease of creating complex structures with nanometer precision. Self-assembled colloidal crystals play an essential role in the formation of photonic crystals. In this article, the assembly of colloidal crystals-silica particles, the synthesis of silica particles, and the assembly of three-dimensional photonic crystals based on inorganic/inorganic and inorganic/organic composites are introduced in detail. The formation of silica based bionic structure material can produce different optical properties of conventional materials. It provides unprecedented opportunities for textiles, pigments, sensing, information encryption, stealth materials, anti-counterfeit marks, energy collection, environmental remediation, and a variety of other application fields.
