Studying the optical properties of hexogen–aluminum composites

Using the photometric sphere, optical characteristics of compressed hexogen tablets (with a density of 1.78 g/cm$^3$) containing aluminum nanoparticles (with a mean diameter of 100 nm) have been studied. A stationary radiation source with a wavelength of 532 nm was used. Coefficients of transmission, diffuse reflection, and absorption of samples have been measured as functions of the mass concentration of aluminum nanoparticles (within the range from 0 to 0.2%). The experimental dependences have been modeled based on solving the equation of monochromatic radiation transfer. The observed dependences of optical properties of the samples under study are satisfactorily described when taking into account the oxide shell on the nanoparticle surface.
