Abstract

The study investigates  the effect of 230 MeV xenon ion irradiation on the optical and luminescent properties of Y3Al5O12:Ce (YAG:Ce)  crystals. Irradiation leads to the formation of Frenkel defects (F, F+), antisite defects, as well as the suppression of Ce3+ ion emission due to the intensification of nonradiation processes and charge transfer Ce3+ Ce4+ . It is shown that with increasing fluence, the luminescence intensity of Ce3+ decreases as a result of the formation of crystals lattice defects such as oxygen vacancies and antisite disorders. Changes in the valence state of cerium (Ce3+  Ce4+) are also possible. The obtained results provide insight into radiation-induced processes in YAG:Ce, which are important for its application in radiation-resistant scintillation detectors.
