“…Furthermore, there should be pointed out the presence of "red" shift of the second and the third maxima Im α@ and "blue" shift of the first maximum under the increase in the thickness of the shell. Such "repulsion" of the surface plasmonic resonances for the spherical bimetallic nanoparticles was predicted in work [73]. Figure 8 shows the graphs of the frequency dependencies Re α@ , Im α@ and | α@ | for the nanoparticles Ag@TC with the different size of the core.…”

“…Let us consider a spherical metallic nanoparticle with the radius 𝑅 𝑐 , covered with the layer of Jaggregate with the thickness 𝑡, located in the medium with dielectric permittivity 𝜖 (m) and which has the total radius 𝑅 = 𝑅 𝑐 + 𝑡 (figure 6). The increase in temperature due to the absorption of light energy by the nanoparticle can be estimated as follows [72,73]…”

“…In fact, ( 4) is an expansion of the total energy in powers of R −1 , implying a well-defined quantity R. However, the atomic-scale surface roughness does not allow one to determine accurately the cluster boundary. Therefore, for example, the scattering of conduction electrons on the surface of nanoclusters is predominantly diffuse, which is important when calculating the optical characteristics of mono-and bimetallic nanospheres [26].…”

“…The possibility of light localization makes it possible to demonstrate, based on the surface plasmon resonance spectroscopy, their efficiency and performance as the hybrid plasmonic waveguides, the biological and chemical sensors, nanoantennas, metamaterials, and the highly reflective coatings (see Refs. [3][4][5] and references therein).…”

“…The complexity of obtaining objects and measurement methods is evidenced by a relatively small number of experiments devoted, as a rule, to quantum size effects [5][6][7][8][9][10][11][12].…”
