Defect-related luminescence of MgO single crystals irradiated with swift 132Xe ions
(2022) In Optical Materials 127.- Abstract
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 intensified with Xe-irradiation fluence up to Φ = 1013 ions/cm2, while drastic emission attenuation in a whole spectral region occurs at higher fluences. The limitations of the use of luminescence methods for the detection of structural point defects induced by heavy... (More)

The limitations of the use of luminescence methods for the detection of structural point defects induced by heavy irradiation have been considered.
