Abstract

Coefficients of transmission, absorption, and reflectance of a composite based on pentaerythritol tetranitrate and spherical cobalt nanoparticles were calculated as functions of sample thickness and mass fraction of metal particles using Mie theory and radiative transfer theory (spherical harmonics method). It was shown that the coefficient of reflectance of light normally incident on the half-space with the plane boundary increased as the Co-particle radius increased. This was because of increases of both the single-scattering albedo and the modulus of the scattering anisotropy factor. The developed method for calculating optical properties of composites based on a transparent matrix with metal nanoparticle inclusions could be used to process experimental light-scattering spectroscopy data.
