Studying the Effect of Successive Irradiation by Electrons and Solar Spectrum Quanta on the Optical Properties of a Nanoparticle-Modified Barium Sulfate Powder
Changes in the structure, diffuse reflectance spectra, and solar radiation absorption coefficients as of the BaSO4 powder modified with SiO2 nanoparticles are studied under successive exposure to electrons and solar spectrum quanta in different sequences. The maximum changes Δas in the absorption coefficient of the BaSO4 powder in the two successive irradiation modes are approximately equal. Irradiation by solar spectrum quanta causes the greatest changes both under the initial exposure and after irradiation by electrons. Regardless of the successive irradiation mode used, defects accumulate mainly in the UV and visible spectral ranges.
