“…Photonic stop-band tuning by the deposition of thin metallic layers on opals and invers opals were reported recently [47]. A similar combination of photonic and plasmonic effects was reported after Au NP infiltration for thin films of photonic crystals with inverse opal structure prepared by photocurable resin polymerization on opal templates [48]. A further possibility for tuning the chemical effects of such hybrid photonic nanoarchitectures may be offered by the phenomenon known in the literature as strong coupling [13,[49][50][51].…”

Porous butterfly wings with hierarchically organized structures from nanometer to centimeter scales were tested as substrates for carrying plasmonic Au and Ag/Au nanoparticles with potential application in photocatalysis. Wings exhibiting structural color generated by chitin-air nanocomposites were used. Hundreds of butterfly species possess these types of color-generating photonic nanoarchitectures, producing color by a similar mechanism to manmade photonic crystals. Artificial photonic crystals are known to enhance photocatalytic processes through the slow light effect. The impact of pure water, water-based sodium citrate solution, and Au and Ag/Au alloy nanoparticles on the optical properties of the natural photonic structures were separated. While water and aqueous sodium citrate solutions change the wing reflectance by the alteration of the wing scale position with respect to the wing plane, Au and Ag/Au alloy nanoparticles form a new, hybrid nanostructure with the chitin nanoarchitecture modifying the structural color of the butterfly wings. The optical properties of the new types of hybrid photonic nanoarchitectures (consisting of butterfly wings and plasmonic nanoparticles) are different from those of the components.

“…Analyzing the propagation distribution reveals that the state distribution corresponding to distinct frequency bands has guiding significance for the production of various functional devices. Additionally, gold has high chemical stability and can significantly enhance the surface Raman scattering of photonic crystals; however, gold is expensive and exhibits relatively weak surface plasmon resonance [13]. The gold-silver alloy nanostructure embodies strong scattering characteristics, which strengthens the Fano resonance signal of the alloy waveguide coupled photonic crystal relative to that of the pure gold structure.…”

In this paper, the transport characteristics of gold/silver mixed chain nanostructures with different proportions of infinite length in the range of 270-810 nm are studied, and the corresponding band gap characteristics and other transport characteristics are analyzed. We introduced an analytical model to determine the complex dielectric constant of an arbitrary composition Au-Ag alloy, and combined this with the experimental data to study the propagation characteristics of the infinitelength gold-silver mixed-chain nanostructures with various compositions. As the gold content exceeds Au : Ag (1 : 2), the coupling coefficient between the forward and reverse waves becomes smaller, and the reverse wave cannot provide enough energy to transfer to the forward wave. The scattering ability of the scattering unit weakens; the frequency range of the propagation state widens; and it exhibits good propagation characteristics. By gradually increasing the proportion of metal in the alloy, we can explore the variation of the propagation characteristics of the alloy. At present, the change of metal propagation characteristics has not been studied from this point, so we found for the first time that frequency modulation can be realized through this method (regulating the attenuation or cutoff frequency range, namely the band gap range). We also studied a cylindrical finite array chain composed of 40 nanorods under five types of experimental data and discussed the wave guiding ability of the finite array chain under the excitation of a plane wave of a specific wavelength.
