Abstract:
The luminescence and optical properties of ceria (CeO2) nanoparticles irradiated by accelerated electrons with an energy of 10 MeV are investigated in this work. CeO2 nanoparticles are prepared by the pulse electron evaporation of a ceramic target with vapor condensation of the evaporated material in a low-pressure gas on a NANOBIM-2 installation. The irradiation of CeO2 nanopowders is found to cause the degradation of their luminescence and optical characteristics. The irradiation of a final aqueous suspension leads to the shift of a photoluminescence band toward the long wave range spectral range in comparison with the irradiation of a nanopowder. The catalytic-like behavior of CeO2 nanoparticles interacting with hydrogen peroxide is analyzed, as well. Nanoparticles modified by the electron beam exhibit the deterioration of their enzyme-like activity.
