“…Consequently, high throughput is achieved, and the rapid fabrication rate and simple process facilitate its application to a large area and in various substrates such as rigid, flexible, and complex structures. In addition, a way to enhance the quality of colloidal self-assembly is demonstrated [180] . The conventional method uses sodium dodecyl sulfate (SDS) after emulsion is introduced at the air–water interface.…”

.Advancements in micro/nanofabrication have enabled the realization of practical micro/nanoscale photonic devices such as absorbers, solar cells, metalenses, and metaholograms. Although the performance of these photonic devices has been improved by enhancing the design flexibility of structural materials through advanced fabrication methods, achieving large-area and high-throughput fabrication of tiny structural materials remains a challenge. In this aspect, various technologies have been investigated for realizing the mass production of practical devices consisting of micro/nanostructural materials. This review describes the recent advancements in soft lithography, colloidal self-assembly, and block copolymer self-assembly, which are promising methods suitable for commercialization of photonic applications. In addition, we introduce low-cost and large-scale techniques realizing micro/nano devices with specific examples such as display technology and sensors. The inferences presented in this review are expected to function as a guide for promising methods of accelerating the mass production of various sub-wavelength-scale photonic devices.

“…The close-packed PS monolayer at the air−solution interface needs to be transferred to the substrate as a template for subsequent nanomanufacturing. The previous transfer methods using solution volatilization or liquid level reduction 48 typically raised the local accumulation of PS nanospheres since the underwater nanospheres adhered to the substrate. Hence, it is also crucial to develop an optimized transfer method to prevent the adhesion of submerged nanospheres.…”

Liquid interfacial self-assembled two-dimensional nanomonolayers are promising as colloidal crystal templates or lithographic masks for the mass production of periodic nanoarrays. However, the interfacial self-assembled monolayers usually suffer various defects such as grain boundaries, line defects, vacancy defects, and multilayers due to imperfect process technology. Here, we demonstrated a series of optimized strategies including the hemispherical-depression-assisted self-assembly, dot coating approach, and vertical lifting transfer protocol to eliminate surface defects especially multilayers jointly. After stabilizing the hemispherical depression height to 1.5 mm with a 40° tilted silicon slide, the self-assembly time was significantly shortened to 10 min for a 1 × 2 cm2 area of PS monolayer. The series of strategies were successfully implemented not only on glass and silicon flat substrates but also on the side and end face of optical fiber, even on flexible substrates, while maintaining great morphologies. Besides, in association with nanospherical lens photolithography and nanosphere lithography technologies, various two-dimensional nanoarrays such as nanotriangles and nanoholes could be successfully obtained for subsequent optical properties research, which present broad application prospects in biochemical sensing, medicine, environmental protection, and other fields.

“…In ref. [256], the electromagnetic energy confinement of an array of polystyrene spheres on an Ag substrate was reinforced by adding a thin Ag coating onto the spheres and a thin TiO 2 passivation layer on the Ag substrate. This configuration provided a 6-fold near-field enhancement of the same structure without the two coatings.…”

Enhancing the light‐matter interactions is important for many different applications like sensing, surface enhanced spectroscopies, solar energy harvesting, and for quantum effects such as nonlinear frequency generation or spontaneous and stimulated emission. Hybrid metal‐dielectric nanostructures have shown extraordinary performance in this respect, demonstrating their superiority with respect to bare metallic or high refractive index dielectric nanostructures. Such hybrid nanostructures can combine the best of two worlds: strong confinement of the electromagnetic energy by metallic structures and high scattering directivity and low losses of the dielectric ones. In this review, following a general overview of the properties of metal‐dielectric nanostructures, some of their most relevant applications including directional scattering, sensing, surface enhanced Raman spectroscopy, absorption enhancement, fluorescence and quantum dot emission enhancement, nonlinear effects, as well as lasing, are summarized.

Enhancing the plasmonic component of photonic–plasmonic resonances in self-assembled dielectric spheres on Ag

Abstract: The plasmonic component of photonic–plasmonic hybrid resonances from a dielectric sphere array on Ag is substantially strengthened by introducing a thin Ag coating and TiO2 passivating layer above and below the PS sphere array, respectively.
