The absorption and scattering efficiencies, albedo and anisotropy factor values were calculated for soot particles in water and pentaerythritol tetranitrate media for different radii in terms of Mie theory. The main features of the calculation results include (i) the domination of absorption over scattering and (ii) the change of attenuation dependence on the wavelength trend at particle’s radius about 150 nm. For smaller particles the attenuation efficiency decreases with wavelength increasing while for bigger ones the trend is just opposite. The soot particles in the experimental part of the work were characterized with dynamic light scattering. The obtained size-distribution is fit well with log-normal distribution having particles’ radius expected value 183 nm. The spectra of total transmittance, ballistic transmittance and diffuse reflectance were measured for studied soot suspension in water. It was shown that the total transmittance does not depend significantly on the wavelength while the diffuse transmittance decreases twice with the wavelength increasing. It is concluded that the calculation results qualitatively agree with the experimental data if the typical particle’s radius is twice smaller than one obtained with dynamic light scattering method. The possible applications of obtained optic properties of soot particles for special devices including optic detonator cups are discussed.
