“…This feature makes our structures potentially useful for security, anti-counterfeiting, camouflage detection, and food safety applications [55][56][57] . They can also help to discriminate metamer materials exhibiting colors indistinguishable by a naked eye 58 . Summarizing, we have successfully engineered a wide range of structural colors in mesoporous alumina samples using internal periodicity, which illustrates the precision and robustness of the design methodology and the fabrication process.…”

Structural colors are a result of the scattering of certain frequencies of the incident light on micro-or nano-scale features in a material. This is a quite different phenomenon to that of colors produced by absorption of different frequencies of the visible spectrum by pigments or dyes, which is the most common way of coloring used in our daily life. However, structural colors are more robust and can be engineered to span most of the visible spectrum without changing the base material, only its internal structure. They are abundant in nature, with examples as colorful as beetles covers and butterfly wings, but there are few ways of preparing them for large-scale commercial applications for real-world uses. In this work, we present a technique to create a full gamut of structural colors based on a low-cost, robust and scalable fabrication of periodic network structures in porous alumina as well as the strategy to theoretically predict and engineer different colors on demand. We experimentally demonstrate mesoporous network metamaterial structures with engineered colors spanning the whole optical spectrum and discuss their applications in sensing, environmental monitoring, biomimetic tissues engineering, etc.

“…Despite a lot of useful research into a certain cure for color blindness based on different medical routes of this disease, important changes in lifestyle remain an open question. These beneficial and useful studies comprised subjects such as gene therapy 5 – 9 , tinted glasses 10 – 13 , lenses 14 – 17 , optical filters 18 , optoelectronic glasses, and advanced features on smartphones and computers 19 – 22 . Tinted glasses with color filters for color blindness correction have been widely investigated and are even commercially available 10 – 13 , 23 .…”

Color blindness, or color vision deficiency (CVD), is an ocular disease that suppresses the recognition of different colors. Recently, tinted glasses and lenses have been studied as hopeful devices for color blindness correction. In this study, 2D biocompatible and flexible plasmonic contact lenses were fabricated using polydimethylsiloxane (PDMS) and a low-cost, and simple design based on the soft nano-lithography method and investigated for correction of red–green (deuteranomaly) color blindness. In addition, the stability test of the fabricated plasmonic contact lenses was investigated into the phosphate buffered saline (PBS) solution and the proposed lens offers an excellent stability into the PBS solution. The plasmonic contact lens proposed herein is based on the plasmonic surface lattice resonance (SLR) phenomenon and offers a good color filter for color blindness correction. The biocompatibility, low cost, stability, and simple fabrication of these contact lenses can offer new insights for applications of color blindness correction.

“…We note that, in principle, the introduction of down-converted light may lead to difficulty distinguishing between converted and visible images (i.e., visible/ultraviolet metamers). This can be avoided for binocular vision if the down-conversion imaging system is applied only to one eye [20].…”

We demonstrate a passive down-conversion imaging system that converts broadband ultraviolet light to narrow-band green light while preserving the directionality of rays, and thus enabling direct down-conversion imaging. At the same time our system has high transparency in the visible, enabling superimposed visible and ultraviolet imaging. The frequency conversion is performed by a subwavelength-thickness transparent downconverter based on highly efficient CsPbBr3 nanocrystals incorporated into the focal plane of a simple telescope or relay-lens geometry. The resulting imaging performance of this down-conversion system approaches the diffraction limit. This demonstration sets the stage for the incorporation of other high-efficiency perovskite nanocrystal materials to enable passive multi-frequency conversion imaging systems.
