“…Therefore, there is a trade-off between decrease of the emitter depth to enhance the interaction with the plasmon and its increase to preserve optical properties. Similar results to the capping layer from 12 to 200 nm were presented in [22]. Formation of the etching cone could be a convenient alternative to enhance the efficiency of the energy transfer from an emitter to the plasmon mode keeping large distance between emitters and the surface.…”

“…In the VLS growth, Au droplets serve as catalysts, and regardless of the materials and substrates utilized, the vapor-phase atoms could diffuse into the liquid-phase Au droplets [17,18]; from the supersaturated Au alloy droplets, the crystallization of NWs can occur at the liquid–solid interface due to the higher sticking probability at the interface [19-23]. In addition, the metallic nanoparticles were utilized in plasmonic applications such as solar cells and light emission enhancement [24-29]. The diameter, size, configuration, and even the density of NWs can innately be determined by those of the Au catalysts, and thus, the control of Au droplets is an essential step for the successful fabrication of the desired NWs.…”

In this paper, the systematic evolution process of self-assembled Au droplets is successfully demonstrated on GaAs (111)A, (110), (100), and (111)B. On various GaAs substrates, self-assembled Au clusters begin to nucleate at around 300°C, and then, they develop into wiggly Au nanostructures at 350°C. Between 400°C and 550°C, the self-assembled dome-shaped Au droplets with fine uniformity are fabricated with various sizes and densities based on the Volmer-Weber growth mode. Depending on the annealing temperature, the size including the average height and lateral diameter and the density of Au droplets show the opposite trend of increased size with correspondingly decreased density as a function of the annealing temperature due to the difference in the diffusion length of adatoms at varied activation energy. Under an identical growth condition, depending on the surface index, the size and density of Au droplets show a clear distinction, observed throughout the temperature range. The results are systematically analyzed and discussed in terms of atomic force microscopy (AFM) images, cross-sectional line profiles, and Fourier filter transform (FFT) power spectra as well as the summary plots of the size and density.

“…The physical origin of the light absorption by metallic NPs is the excitation of coherent oscillations of the conduction band electrons by light, which is known as surface plasmon resonance (SPR) [1]. Recent investigations showed that SPR-based devices have enhanced properties useful for many optoelectronic materials and devices, such as solar cells [2] or emitters [3]. Dense silica matrices, doped by NPs of noble metals, have stimulated considerable interest in basic research as well as from the applied standpoint in connection with enhancement of catalytic behavior [4], sensors [5], linear and nonlinear optical properties [6-9].…”

H2-induced copper and silver nanoparticle precipitation inside sol-gel silica optical fiber preforms

Ionic copper- or silver-doped dense silica rods have been prepared by sintering sol-gel porous silica xerogels doped with ionic precursors. The precipitation of Cu or Ag nanoparticles was achieved by heat treatment under hydrogen followed by annealing under air atmosphere. The surface plasmon resonance bands of copper and silver nanoparticles have been clearly observed in the absorption spectra. The spectral positions of these bands were found to depend slightly on the particle size, which could be tuned by varying the annealing conditions. Hence, transmission electron microscopy showed the formation of spherical copper nanoparticles with diameters in the range of 3.3 to 5.6 nm. On the other hand, in the case of silver, both spherical nanoparticles with diameters in the range of 3 to 6 nm and nano-rods were obtained.
