| Abstract: | Effects exerted on plasmon absorption spectra by different characteristics of aggregating silver sols with a fractal distribution of particles whose sizes are in the range 5–30 nm are studied by mathematical simulation with the aid of a modification of the method of coupled dipoles. Distinctive features of plasmon absorption contours of silver sols having different particle-size distribution functions and different properties of the adsorption layers of the particles are explained. |
