摘要: The nature and topological distribution of optical centers within various regions hot pressed disks transparent magnesium aluminates spinel ceramics doped with LiF were studied. In the absorption spectra this type ceramic, bands revealed at 4.75 eV 5.3 eV, which identified Fand F-centers, respectively. Because both are formed by anionic vacancies captured one or two electrons, was determined. band 5.65 also found is tentatively complex that capture fluorine ions electrons. Using X-ray irradiation variety hole related to cationic established. spatial ceramic disk
