“…Therefore, bulks or relatively thick-layer specimens are used for these purposes. Some bulks are polycrystalline, prepared by direct synthesis of elements, − others are monocrystalline, obtained by the means of Bridgman and zone melting technologies. − But most of the samples are in the form of polycrystalline layers, prepared by almost all possible physical methods for deposition, as thermal deposition in vacuum, ,− arc melting, laser ablation, magnetron sputtering, − ion implantation, etc., either from preliminary synthesized bulks or from the initial elements, as the last are either coevaporated ,− or deposited by alternating layered structures. ,,, The chemical reactions for formation of the desired compounds are realized either by solid-state self-assembly of the components , or by further thermal annealing. ,, …”

We present a review of phase formation tendencies, methods for preparation and optical properties of alloys and compounds from the binary systems of silver or gold with metals and metalloids from the p-block of the Periodic system of elements. Reference data about the homogeneity regions in the systems of interest, together with information about the crystalline structure of existing indexed compounds in them, is proposed and statistically analyzed. General background for the synthesis of intermetallic alloys and compounds, and the tendencies for their preparation for plasmonic purposes are presented. The high plasma frequency, ω p of p-block metals makes their alloys with silver and gold an interesting object of study, due to the possibility of ω p variation over a wide interval in the ultraviolet (UV) spectral region with a view to finding more efficient materials for excitation of a localized surface plasmon resonance (LSPR) necessary for various applications and techniques operating in this part of the electromagnetic spectrum. Unlike the alloys between the noble metals Cu, Ag, and Au, which form continuous series of solid solutions, different areas can be observed in the phase diagrams of the Ag(Au)−p-block systems, containing solid solutions, intermetallic compounds, and heterogeneous mixtures. The ability to vary the plasma frequency of solid solutions, like the alloys between the noble metals Cu, Ag, and Au, is the reason to pay attention to the compositions of the Ag(Au−p-block systems that fall in these regions of their phase diagrams. The analysis of the published results for complex permittivity shows that the addition of small amounts of conductive p-block elements to noble metals reduces the energy gap for interband transitions and increases their plasmonic activity in the UV spectral range. The article analyzes the relationship between electrical resistivity and LSPR excitation efficiency, which shows that the intermetallic compounds from Ag(Au)−p-block systems with a well-ordered crystalline structure and good conductivity level can be more effective materials for UV plasmonics than the boundary solid solutions. Intermetallic compounds can be easily obtained in the form of bulk samples, thin films, and nanoparticles with controlled size and geometric shape. The spectral dependences of the plasmon efficiency of the intermetallic compounds, determined from their complex permittivity functions, show that they are promising materials for excitation of LSPR in the UV spectral region.

“…The first is based on the "top-down" principle, where the material is removed through femtosecond laser fabrication to obtain the nanostructures with specific shapes and sizes. The second category is based on the "bottom-up" principle, based on the chemical properties of self-assembly to grow new structures on top of the original structure to form a basic surface micro-nanoarranged structure, the main methods include multi-photon polymerization [29,30], metal salt solution reduction [31,32], metal particle sintering [33,34], and laser-induced forward transfer [35].…”

Noble metal plasmonic nanostructures have a wide range of applications in surface-enhanced Raman scattering (SERS), solar energy conversion, optical imaging, biosensing, and many other fields due to their unique localized surface plasmon resonance effects and optical properties. In recent years, the fabrication method of noble metal plasmonic nanostructures has attracted a lot of research interest. Compared with traditional processing methods, femtosecond laser processing has the advantages of high processing resolution, small heat-affected zone, high processing flexibility, controllability, and ease of patterning, and has shown great potential for application in the fabrication method of noble metal plasmonic nanostructures. In this paper, the recent advances in the fabrication of noble metal plasmonic nanostructures by femtosecond laser are reviewed, followed by a discussion of the characteristics, advantages, and potential applications of the structures prepared by this method.

“…PLD in open air could also lead to the formation of highly porous structures on different substrates [ 19 , 21 ]. Our previous results showed that the morphology of gold structures produced by PLD in open air depends on the target–substrate distance, laser fluence, number of laser pulses applied, and the laser wavelength used [ 23 – 24 ]. Furthermore, a decrease in the target–substrate distance below 3 mm resulted in the formation of denser, larger structures compared to deposition at larger distances [ 23 ].…”

We present a fast and flexible method for the fabrication of Au nanocolumns. Au nanostructures were produced by pulsed laser deposition in air at atmospheric pressure. No impurities or Au compounds were detected in the resulting samples. The nanoparticles and nanoaggregates produced in the ablated plasma at atmospheric pressure led to the formation of chain-like nanostructures on the substrate. The dependence of the surface morphology of the samples on the deposition geometry used in the experimental set up was studied. Nanocolumns of different size and density were produced by varying the angle between the plasma plume and the substrate. The electrical, optical, and hydrophobic properties of the samples were studied and discussed in relation to their morphology. All of the nanostructures were conductive, with conductivity increasing with the accumulation of ablated material on the substrate. The modification of the electrical properties of the nanostructures was demonstrated by irradiation by infrared light. The Au nanostructures fabricated by the proposed technology are difficult to prepare by other methods, which makes the simple implementation and realization in ambient conditions presented in this work more ideal for industrial applications.
