Vielhauer}, howpublished={online}, abstract={Absorption, emission and excitation spectra of 50 MeV electron beam irradiated and as-grown YAG single crystals were studied and compared in the 10-300 K temperature range using time-resolved luminescence spectroscopy under UV/VUV/XUV excitation by synchrotron radiation and cathodoluminescence. The emission spectra consist of intrinsic (excitonic) and defect related non-elementary bands in the VIS/UV range. It is shown that fast electrons create stable F and F+ color centers with characteristic emission and absorption bands in the visible/UV range. Induced absorption caused from these defects starts at 4.2 eV. Energy transfer from host to color centers is not efficient process.}, type={Article}, title={Investigation of Luminescence Processes in YAG Single Crystals Irradiated by 50 MEV Electron Beam}, keywords={Physics, Electromagnetism; electron and ion optics, Optics}, }
