“…The orientation of the short-range ordered crystal is equivalent along all the directions, thereby the coherent light can be uniformly scattered to different viewing angles through the amorphous structures. [63,64] In addition, angle-resolved spectra (Figure 3f,g) of APCs show that the reflection peak of the film was almost unchanged under different viewing angles, further proving the non-iridescent structural color of APCs.…”

printing, [23][24][25][26][27][28][29] anticounterfeiting, [30][31][32][33][34][35][36][37][38] photo catalysis, [39][40][41] optical device, [42][43][44][45][46] and solar energy. [47][48][49][50] According to the order degree of the structures, the PCs can be divided into highly ordered photonic crystals (OPCs) and amorphous photonic crystals (APCs). These two kinds of PCs show considerable difference in the optical properties. The OPCs with long-range ordered structures show iridescent structural colors, while the APCs with only short-range order exhibit non-iridescent structural colors. For some applications, such as color displays or sensors, [51][52][53][54] angle independent colors are necessary and required. In this regard, APCs with angle independent structural colors show inherent advantages than the OPCs owing to the amorphous packing of the particles. However, the fabrication of APCs remains a big challenge. In particular, the charged colloidal particles tend to crystalize and form long-range order upon the assembly process, which make it rather difficult to prepare APCs.Recently, there have been attempts to fabricate APCs through the dynamic or thermodynamic controlling the assembly process. Spray [55,56] and infiltration [57] are efficient in preparing APCs based on the rapid remove of solvents from the colloidal solution, respectively. In both approaches, the fast remove of solvents will break the longrange packing tendency of particles, resulting in the shortrange order. However, the usage of the environmentally harmful solvent or porous substrates in these two methods will limit their practical utility. Layer by layer strategy [58] is promising in preparing APCs based on consecutively polyelectrolyte coating process but subjected to the tedious and time-consuming processes. Although the bi-disperse suspension [59,60] is successful for fabrication of APCs, it is essential to control the difference in particle size to guarantee the bright colors of APCs. Alternatively, APCs can be fabricated by the self-assembly of soft particles. [61,62] With this approach, subtle fabrications must be well controlled to ensure the success of controlling the thickness of the shell and the assembly of soft particles. Except for the fabrication, the APCs usually exhibit pale structural colors due to the strong multiple scattering light. To deal with this problem, carbon black or other black particles are introduced into the APCs to absorb the Facile and efficient fabrication of amorphous photonic crystals (APCs) with uniform and angle independent structural colors is highly desired due to their unique applications in non-iridescent colors-based displays, pigments, and sensors. Here, a solvent-assisted colloidal assembly approach is reported to fabricate APCs with uniform and angle-independent structural colors by the self-assembly of polydopamine-embedded silica particles in pentanol. The surface charge of the particle mediated by the polarity of solvent is demonstrated to be the key to control the particle arrangeme...

methods rely on clonable labels produced by a deterministic process. These labels are low-cost but their simple and repeatable preparation processes and regular decoding mechanisms are exploitable by counterfeiters. [4,5] Many of the more complex and safer anti-counterfeiting labels (such as high-end RFID labels with large number of logic gates) cannot become standard on some commonly used products due to their high cost. [5,6] Anti-counterfeiting labels with physical unclonable functions (PUF) are a feasible solution to the above shortcomings. Since the introduction of the PUF in 2002, [7] many anticounterfeiting labels with different PUF characteristics have been developed, such as unique bionic fingerprint pattern with random surface topography; [8][9][10] randomly distributed nanoparticle pattern, including flower-like patterns with random pinning points, [11] nanowires coated with fluorescent dyes in random positions, [12] etc. In addition, researchers have prepared many types of PUF anticounterfeiting labels with optical response. For example, Cheng et al. [13] reported a multicolor plasma nanopaper with random Raman intensity distribution, He et al. [14] designed multi-mode structural-color anti-counterfeiting labels composed of randomly arranged nanospheres, and Leem et al. [15] developed edible silk film labels with random light response.

“…[75][76][77][78][79][80][81][82][83] A noniridescent structural colour pattern originates from the breakage of a longrange ordered structure and assembly of a short-range ordered structure. 69,[84][85][86][87][88][89][90][91][92][93][94] Various processes are used for the preparation of short-range ordered structures for noniridescent structural colour patterns, such as spraying a mixture of two differentsized particles, 95 atomization deposition of a silica nanoparticle dispersion accompanied by an additive, poly(vinyl alcohol) (PVA), 24 and stretching the composite film to form short-range ordered nanovoids in the local strain region. 22 Particularly, adding black matter (such as graphene or cuttlefish ink particles) to the amorphous structure is beneficial for yielding bright, highly saturated and brilliant noniridescent structural colour patterns.…”
