Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | There were provided the comparative investigations of the efficiency of optical absorption centers formation in magnesium
aluminates spinel (single crystals and ceramics) at the influence of high energy gamma or electron beams.
It was revealed that at gamma irradiation in the single crystals and ceramics the most probably the hole centers
are formed which were created primarily at growth defects: cationic vacancies and anti-site defects. After electron
irradiation of different fluences in absorption spectra there were observed bands related to hole centers (defects in
the cationic sub-lattice) which practically does not change, while the concentration of electron centers (defects in the
anion sub-lattice) grows proportionally to the electron fluence. |
