Abstract
A comparative analysis of the structure, phase composition, morphology, and diffuse reflection spectra in the region of 0.2–2.5 μm is carried out. Their changes arising from the bombardment of microand nanopowders of yttrium oxide with 100-keV protons and 100-keV electrons is examined. It is found that the reflectance of the nanopowders in the near-IR (infrared) region is less than that of the micropowders and, upon electron bombardment, their radiation resistance is slightly larger as compared to the micropowders.
