Effect of gamma irradiation on NaVO3 in polycrystalline solid state
2020
Chemical Reports
Preserved Fulltext
An EPR study of the paramagnetic centers formed by γ irradiation of polycrystalline NaVO 3 , at 77 K and room temperature was performed. According to their EPR parameters and thermal behaviour, the centers were attributed to: VȮ 3 , VȮ 2− 3 , VO, VO + andȮ − 2 radicals. The spin-spin relaxation time was calculated from the derivative peak-to-peak line widths assuming Lorentzian lines. A mechanism of the paramagnetic species formation was proposed.
