摘要

研究了二氧化硅纳米粒子修饰的硫酸钡粉末在不同序列的电子和太阳光谱量子连续照射下的结构、漫反射光谱和太阳辐射吸收系数的变化。在两种连续辐照模式下，BaSO4 粉末吸收系数的最大变化 Δas 大致相等。太阳光谱量子辐照引起的变化在初始辐照和电子辐照后都最大。无论采用哪种连续辐照模式，缺陷都主要在紫外和可见光谱范围内积累。

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 a_s 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 Δa_s 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.
