Abstract
Resonance properties of the local field of metal fractal clusters are considered. The effects of surface-enhanced Raman scattering, photoluminescence enhancement, and nonlinear responses are studied. It is demonstrated that the Rautian’s model based on the quantum theory of nonlinearity offers a more accurate description than previous theories. Among the scientific results of the theory proposed by Rautian and his team, the following can be highlighted: metal nanoparticles with a diameter of \(<\)30 nm exhibit discrete energy levels, in contrast to semiconductor quantum dots, the Rautian’s theory provides an accurate description of the linear part of the dielectric function corresponding to the classical Drude model; the cubic nonlinear susceptibility according to the Rautian’s model agrees with experiment, indicating a contribution of the conduction electrons.
