SiO2amorphous nanopowder (NP) is produced with the specific surface area of 154 m2/g by means of evaporation by a pulsed electron beam aimed at Aerosil 90 pyrogenic amorphous NP (90 m2/g) as a target. SiO2NP nanoparticles showed improved magnetic, thermal, and optical properties in comparison to Aerosil 90 NP. Possible reasons of emergence of d0ferromagnetism at the room temperature in SiO2amorphous NP are discussed. Photoluminescent and cathode luminescent properties of the SiO2NP were investigated.

AbstractThe results of the study of the degradation of thermoluminescent materials Li_2B_4O_7:Be + Mn and Li_2B_4O_7:Zn + Mn under the effect of radiation (pulsed electron beam) and laser radiation are presented. As a result of exposure to high doses of radiation, the structure of the samples under study partially acquires an amorphous character, while the effect of radiation exposure is manifested in the optical properties in the appearance of green luminescence due to manganese centers in the tetrahedral environment. With subsequent irradiation with a laser at a wavelength of 350 nm, luminescence centers decay due to photochemical oxidation of manganese by the reaction of Mn^2+ → Mn^3+. It is shown that Li_2B_4O_7:Be + Mn has a lower radiation resistance than Li_2B_4O_7:Zn + Mn.
