Abstract

The effects of proton and electron (E = 100 keV, F = 5 × 10 ¹⁵ cm^-2) exposure on the reflective spectra of SiO ₂ micro- and nanopowders in wavelength range from 250 to 2500 nm have been investigated. It has been established that the reflectance and radiation stability of nanopowders is less than that of micropowders. This effect is caused by the high concentration of radiation defects, which act as surface absorption centers (Es′ centers) near the energies 5.47 and 4.45 eV, and peroxide silicon defects (SiOOSi) near the energy 3.84 eV.
