On the Structure of Luminescenting Centers in Lu2SiO5:Се Crystals

详细

The absorption and luminescence spectra of cerium-activated lutetium oxyorthosilicate crystals Lu₂SiO₅:Се subjected to irradiation by gamma rays and neutrons and thermal treatment under reductive conditions have been studied. It has been demonstrated that the radiative and thermal treatment of crystals leads to the removal of oxygen from the oxygen heptahedrons surrounding cerium ions with the conversion of Ce1 centers into Ce2.
