Size Effect on the Radiation Stability Silicon Dioxide Sphere Particles
Статья в журнале
The effect of protons (E = 100 keV, F = 5×1015 cm-2) exposure on the diffuse reflectance spectra of the SiO2 with different size particles in wavelength range from 250 to 2500 nm have been investigated. Particles were nanosphere, submicrosphere, microsphere and submacrosphere, as well as solid micro- and nanocrystals. The synthesis of the particles was carried out by the formation of silica shells and dissolution of the polystyrene core particles. The surface morphology, surface area and crystal structure of the particles have been investigated. When evaluating the changes of the solar absorptance, it was found that the radiation stability of the micro- and submacro-hollow particles is higher than that of the other nanostructured particles, except for solid microcrystals. The low radiation stability of the hollow microparticles is due to the large void inside the hollow particles where radiation defects are not formed.
