Laser synthesis of gold nanostructures at atmospheric pressure: Nature and applications

Physics of Laser-Induced Plasma Streams Under Irradiation of Metals with Nanosecond Laser Radiation Pulses at Atmospheric Pressure

“…On the other hand, recent works [19][20][21][22][23][24], because of their narrow practical purposefulness, are characterized by widely disconnected topics, and, therefore, it is very diffi cult to reconstruct on their basis the integral physical picture of the phenomenon under investigation. However, the results of a number of works [25][26][27][28] show that the processes of plasma initiation under the action of high-power nanosecond laser pulses on metals in air can serve as the basis for developing effective technologies of laser treatment, including those aimed at bulk [29][30][31] and surface [32] modifi cation of functional materials by metal nanostructures.…”

“…Figure 6c shows the characteristic radiation spectrum of a conic nanoobject excited by a narrow-focus electron beam (electron probe), which points to the fact that the formed nanostructures consist solely of the target material. Such nanostructures permit, for example, modifying the optical properties of the surface (due to the surface plasmon resonance effect) of silicon photocells with the aim of upgrading their effi ciency in the near-IR region [32].…”
