“…as photonic noses. 68,72 We were able to show that different polar protic vapors could be distinguished from non-polar vapors by recording the time dependent optical shift of a HSbP 2 O 8 /TiO 2 1D PC. 72 Using this combined read-out of spectral shift and response time, even constitutional isomers among the polar and protic vapors could be differentiated (Fig.…”

“…The main reason for this high selectivity is due to the acidic nature of the nanosheet layer, which is able to selectively interact with polar protic analytes through hydrogen bonding and acidbase interactions. 72 Graphene oxide thin films were also able to distinguish between polar protic vapors (see Fig. 5b).…”

The ability to produce structural color from inherently colorless materials, similar to that in butterfly wings and beetle shells, has attracted considerable research interest over the last three decades. Despite their extraordinary properties and performances, the field of structural colors based on inherently functional 2D materials only took off recently. In this minireview, we highlight the diversity of 2D materials utilized for achieving structural coloration in different architectures. We summarize the large tunability of photonic architectures based on 2D materials and emphasize their extraordinary dynamic response induced by external stimuli. Subsequently, recent strategies to tailor their properties with molecular and structural approaches are discussed. Finally, we point out promising future directions in this emerging field.

Eng., 2019, 4, 566-579 This journal is Design, System, ApplicationAs 2D materials are coming of age, their richness in composition, structure and properties offer a unique platform for the design of tailor-made nanoscale building blocks for functional devices. Combining the chemical scope, diverse optical properties and stimuli-responsive nature of 2D materials and their ensembles with the recent advancement in liquid-assisted assembly strategies, 2D materials have emerged as versatile building blocks in thin film-based photonic architectures, including Fabry-Pérot interference filters and 1D photonic crystals. To impart such architectures with maximum functionality, design strategies range from molecular level approaches such as ion exchange and intercalation, to morphology engineering such as porosity tuning. The integration of 2D materials into photonic architectures has opened up new horizons in the realization of smart devices, ranging from vapor and pressure sensors to functional surfaces allowing for the touchless tracking of finger motions. On a more fundamental level, thin films exhibiting tunable structural color allow for the observation of otherwise optically silent processes with the naked eye, such as intercalation into 2D materials. Cast into photonic architectures, the unique versatility of 2D materials and their molecularly engineered counterparts can be harvested to push the limits of label-free sensing, anticounterfeiting, radiation shielding, photovoltaics, display technology, and beyond.

“…Besides, a new type of photonic nose, based on the BSs consisting of swellable HSbP 2 O 8 nanosheet, can distinguish water vapor, nonprotic (nonpolar and polar), and protic solvent vapors (alcohols). The saturation time and color shift were two main descriptors . A mesoporous silica colloidal crystals sensor is capable of quantitative discriminating chemical vapors according to the indication of the fluorescence and reflectance spectra.…”

known that the optical properties related refractive index is an important parameter for ordered micro/nanostructures. Commonly, organic substances own lower refraction. Aiming at improving which, researchers introduce highly polarizable heteroatoms or rigid aromatic moieties. However, the maximum of refractive index is limited to 1.54-1.60, [3] which is far from the requirements of rapidly developing technologies. [4] Incorporation of inorganic materials with relative higher refractive index (TiO 2 , ZnO, ZnS, graphene nanoparticles, and Si) into an organic matrix is capable of enlarging the optical parameters to a great extent, generally up to a value of 2.5-3.0, [5] which offers more chances for the fabrication of novel ordered micro/nanostructures. Photonic crystals (PCs), for example, regularly arrange materials of high and low dielectric constants on the order of the wavelength of light. The photonic bandgap (PBG) prohibiting the propagation of light results from the sufficient dielectric contrast and appropriate geometry. The structural color therefore generates. Manipulating the propagation of light via micro/nanostructures meets the requirements for modern optical devices. [6] As a result, more efforts have been applied to devices consisting of micro/nanostructures of multiple materials, such as synthetic materials and biomaterials. [7] Besides optical properties, the strength and toughness of ordered micro/nanostructures are also improved based on the hybrid material. Meanwhile, the electric and magnetic features of inorganic dopants can also exactly assist the adjustability. Therefore, the hybrid can significantly improve performance compared with its constituent.This review emphasizes on applications sought (sensing, imaging, communication, photoelectricity, etc.), the materials used (silicon, metals, polymers, etc.), and the preparation methods employed (patterning, etching, deposition, etc.). We present an attempt to classify and compare some intensively reported micro/nanostructures of hybrid materials and/or heterogeneous structures, along with recent important developments in literatures. It is organized as follows: First, we summarize some fundamental physical principles and concepts in brief. Second, we particularly highlight artificial and natural laminar structures, represented by Bragg stacks (BSs) and butterfly wings, which have drawn much attention in the latest literatures. Next, the focus shifts to the preparation routes and materials adoption of colloidal crystals and their derived periodic arrays. A few examples of highly functional materials Recent advances in manufacturing and technology of ordered hybrid micro/ nanostructures have acquired many breakthroughs. With the aid of the cooperation of various materials, the ordered hybrid micro/nanostructures exhibit high-quality performance and mechanical stability and allow the modulation on the light-matter interaction in a controllable manner, thereby enabling a wide variety of innovative applications.
