“…[112] Recently, fluoride-containing eutectic salts with rod structures (of KCl-LiF and NaCl-LiF eutectic) have been studied for their polaritonic properties as they can behave as metamaterial waveguides with near-zero permittivity (so-called epsilon-near-zero metamaterials) or exhibit absorption-induced transparency. [117] Finally, the combination of a metal-dielectric eutectic system composed of Ag and Bi 2 O 3 was recently explored for its localized surface plasmon resonance properties. A broadband visible to mid-IR optical quality glass was obtained using a CaSiO 3 -Ca 3 (PO 4 ) 2 eutectic.…”

polarizers, some waveguides, and many lasers. [1][2][3] Materials with powerful optical functionalities, including negative-index of refraction and optical chirality, can be realized by appropriate placement of materials with suitable properties in 2D or 3D space. [4][5][6] Light in the visible spectrum can be manipulated, although the tolerance for defects is exceedingly low at visible frequencies, and the number of materials with the appropriate properties is limited. [7,8] Most photonic crystals are fabricated by high-resolution top-down 2D patterning methods such as electron-beam lithography, interference lithography, and focused ion beam milling. [9] However, it is challenging to fabricate large-area bulk materials with these techniques, especially with intricate internal structures. [8] Additionally, many materials with promising optical properties are not compatible with these top-down patterning methods. [4,10] As work on colloidal crystals has shown, controlled self-assembly is an effective route to organizing materials into 3D architectures, which interact strongly with light. [9][10][11][12][13] Colloidal self-assembly, however, only offers a limited set of symmetries (generally those of close packed arrangements), and a spherical basis. [12] For many applications, considerably more complex structures are of interest. Particularly promising approaches for forming materials with complex internal microstructures include eutectic solidification and block copolymer self-assembly, [14][15][16][17] and materials with interesting optical properties have been reported using both approaches. These methods are advantageous due to the wide range of microstructures they form. Here, we focus on the structures formed by eutectic solidification since materials with a broader range of optical properties are available compared to that provided by block copolymers, and because the characteristic lengths of structures accessible through eutectic solidification better match the wavelengths of visible and IR light. Further, forming materials with sufficiently large characteristic dimensions for interaction with visible light by block copolymer assembly is synthetically challenging as it requires high molecular weight polymers. [18] Similarly, self-assembly of other building blocks, e.g., nanoparticles, [19,20] molecules, [21,22] and DNA, [23,24] tend to produce structures with characteristic dimensions too small to provide strong light-matter interactions (via diffractive phenomena), [2,3,25] and are thus not the emphasis of this review.Mesostructured materials can exhibit enhanced light-matter interactions, which can become particularly strong when the characteristic dimensions of the structure are similar to or smaller than the wavelength of light. For controlling visible to near-infrared wavelengths, the small characteristic dimensions of the required structures usually demand fabrication by sophisticated lithographic techniques. However, these fabrication methods are restricted to producing 2D and a limited range of 3D...

“…Eutectic solidification enables crystallization of a two-phase solid, often with an interesting selforganized micro-/nanostructure (typical are rod-like and lamellar structures) from a miscible liquid phase at a certain temperature [25]. Eutectic composites have been investigated for various applications such as solar energy conversion [26][27][28], power generation gas turbines [29], scintillators [30,31] or second-harmonic generators [32]. The plasmonic effect was presented in a eutectic composite for the first time with a Bi 2 O 3 -Ag composite [21,22].…”

Evolution of silver in a eutectic-based Bi2O3–Ag metamaterial

et al. 2017

The development of novel manufacturing techniques of nano-/micromaterials, especially metallodielectric materials, has enabled dynamic development of such fields as nanoplasmonics. However, the fabrication methods are still mostly based on time-consuming and costly top-down techniques limited to two-dimensional materials. Recently, directional solidification has been proposed and utilized for manufacturing of volumetric nanoplasmonic materials using the example of a Bi 2 O 3 -Ag eutectic-based nanocomposite. Here, we explain the evolution of silver in this composite, from the crystal growth through the post-growth annealing processes. Investigation with tunneling electron microscopy shows that silver initially enters the composite as an amorphous AgBiO 3 phase, which is formed as a wetting layer between the grains of Bi 2 O 3 primary phase. The post-growth annealing leads to decomposition of the amorphous phase into Bi 2 O 3 nanocrystals and intergranular Ag nanoparticles, providing the tunable localized surface plasmon resonance at yellow light wavelengths.

“…The activation energy Ea was determined from these measurements at 137-144 kJ mol -1 , which fits well with the one determined by DSC (139 kJ mol -1 ). 3-NBA exhibits two stable centrosymmetric polymorphs [40,41], labeled 3-NBA LT and 3-NBA HT for the low-and the high-temperature form, respectively, but 3-NBA crystallized from acetone showed a new XRPD pattern and an SHG activity comparable to that of the quartz reference [27]. In this study, P-SHG and TR-SHG have proved their relevance in detecting very small amounts of structural impurity in the commercial product, but also in studying its stability depending on time and temperature.…”

The application of powder second harmonic generation (P-SHG), temperatureresolved SHG (TR-SHG), and SHG microscopy (SHGM) in the characterization of bulk crystalline samples is illustrated. P-SHG applied to powder samples can be an extremely sensitive approach to detect the absence of an inversion center in crystalline structures, TR-SHG serves to monitor temperature-induced phase transitions, and SHGM is used in the detection of non-centrosymmetric zones inside a heterogeneous material. These methods are of great relevance, e.g., in the pharmaceutical industry where crystalline active pharmaceutical ingredients are often made of a single enantiomer and are therefore non-centrosymmetric. Herein, several examples are provided to describe how a given SHG signal should be interpreted. A general procedure to carry out a P-SHG experiment is illustrated in detail.
