Modelling degradation of optical properties for BaSO₄ pigments modified by nanoparticles under irradiation with charged particles

Статья в журнале

The authors propose a model for the physical processes that occur under ionizing irradiation in BaSO₄ powders modified with SiO₂, Al₂O₃, and ZrO₂ nanoparticles. The model is based on physical representation and on the experimentally obtained correlation between spectra, solar absorptance, nanoparticle concentration, and accelerated electron fluence. The model includes four constituents, two of which describe accumulation of defects solely for initial irradiated powders. In case of irradiated BaSO₄ powders, accumulation processes are described via all constituents. The changes in optical properties have been predicted and calculated under electron spectra exposure at the geostationary orbit within 15 years period.
