Color centers induced by proton exposure in aluminum oxide hollow particles

Статья в сборнике трудов конференции

The effects of proton (E = 100 keV, F = 54×1015сm–2) exposure on the reflective spectra of Al2O3 hollow particles in wavelength range from 250 to 2500 nm have been investigated. Hollow particles were obtained by deposition nanoparticles on polystyrene balls in chitosan solution with subsequent heat treatment. X-ray photoelectron spectra of the material were analyzed for the O1s peak before and after irradiation. It has been established that radiation stability of the hollow particles is higher than that of Al2O3 microparticles. This effect is caused by the low concentration of color centers in the hollow particle due to lack of material in the bulk of particles.
