The absorption and scattering efficiency factors for cobalt nanoparticles over wavelengths ranging from 400 – 1200 nm were calculated. The maximum values and corresponding radii of the absorption efficiency were shown to be dependent upon the incident light wavelength. The highest scattering factor values in the studied spectral range were between 2.2 and 2.4. If the absorptivity of the matrix increases, absorption of the light by cobalt nanoparticles begins to dominate over scattering process. The obtained results allow us to predict the optical properties for composite materials based on a transparent matrix with cobalt nanoparticles, which is essential for the accurate modeling of such systems’ behavior under laser irradiation.
