“…Figure 3 shows the curves of the frequency dependencies for the imaginary parts of the diagonal components of the dielectric tensor for particle Table 1. The parameters of metals (see, e.g., [36,37] Optical absorption of the composite with the nanoparticles, which are covered with the surfactant layer Au@OAm. Let us point out that, as in the case of the dependencies 𝑅𝑒𝜖 @ ∥ (ℏ𝜔), the dependencies 𝐼𝑚𝜖 @ ∥ (ℏ𝜔) (Fig.…”

“…As a result, the whole picture of resonances became shifted by about double frequencies, but the size-induced red and blue shifts did not change qualitatively. 3 Thus, formula (10) describes the resonances only partially. An analogous formula for a bimetallic sphere has to make allowance for a substantial number of metal parameters (see Table ), as well as the radii of the core and the shell.…”

“…Such a variety of potential nanoparticle applications is possible, first of all, due to the appearance of a plasmon resonance. The shape and position of the plasmon resonance peak depend on the particle size and shape, as well as on the heterogeneity of particle conglomerates [1,9,10]. Therefore, those parameters can be adjusted by selecting the corresponding synthesis conditions, which is especially important for creating the information processing devices and for the development of subwavelength optical devices, plasmon nanoantennas, and nanolasers, as well as elements of optical schemes and photodetectors [11].…”

“…Вирази цiєї теорiї було адаптовано для металевих наноцилiндрiв i нанодискiв (див. роботи [36,37]), а також для шаруватих сферичних наночастинок [38,39]. Але питання про механiзми релаксацiї у металевих острiвцях на дiелектричнiй пiдкладинцi дотепер не дослiджувалося.…”
