title = "The optical properties of magnesium oxide containing transition metal ions and defects produced by fast neutron irradiation",
abstract = "The photoluminescence (PL), its excitation (PLE) and optical absorption of MgO crystals containing transition metal ions and defects produced by fast neutron irradiation fluence up to 1020cm-2(E>0.1 MeV) are investigated. Three range of luminescence are observed: 380-460 nm, 650-850 nm and 850-1050 nm. These luminescence bands are attributed to presence of Fe3+. We assume that the 440 nm photoluminescence band belongs to the complex V-OH-Fe3+ center with tetragonal symmetry, while the ∼730 nm PL band observed in the irradiated MgO crystals is connected with defects, generated as a result of decay of the complex V -OH-Fe3+ centers. The near infrared luminescence bands in MgO crystal are connected with the Fe3+- Fe3+exchange coupled pairs. Furthermore the luminescence of chromium and manganese ions of different symmetry is observed.",
