Defect-related luminescence of MgO single crystals irradiated with swift 132Xe ions
Low-temperature cathodo- and photoluminescence connected with the F and F+ centers (oxygen vacancies in different charge states) and bivacancies have been investigated in MgO single crystals preliminarily irradiated by 230-MeV 132Xe ions with varying fluence (up to 1014 ions/cm2). The cathodoluminesence bands (result of decomposition into Gaussians) related to the F, F+ and P centers have intensif
