Abstract: The impact of 230-MeV Xe$^{132}$ ion irradiation on the structural, optical, and lumi-nescent properties of YAG:Ce single crystals is investigated over a fluence range of 10$^{11}$–10$^{14}$ ions/cm$^2$. Optical absorption; cathodo-, X-ray, and photoluminescence; andX-ray diffraction are employed to analyze radiation-induced changes. Irradiation leadsto the formation of Frenkel (F, F+) and antisite defects and attenuates Ce$^{3+}$ emission (viaenhanced nonradiative processes and Ce$^{3+}$ → Ce$^{4+}$ recharging). A redistribution betweenthe fast and slow components of the Ce$^{3+}$-emission is considered. Excitation spectra showthe suppression of exciton-related emission bands, as well as a shift of the excitation onsetdue to increased lattice disorder. XRD data confirm partial amorphization and a high levelof local lattice disordering, both increasing with irradiation fluence. These findings provideinsight into radiation-induced processes in YAG:Ce, which are relevant for its applicationin radiation–hard scintillation detectors.
