Abstract
Optical and luminescence characteristics of Lu2+2ySi1-yO5+y (LFS) scintillation crystals are studied before and after irradiation with doses to 45 Mrad from a 60Co source. LFS crystals were doped with Ce3+, Sc3+, Ca2+, and Y3+ ions with various concentrations. The dependence of the radiation resistance of LFS crystals on Ce ion concentration is detected. For the crystal of composition Ce:Sc:Ca:Y:LFS, it was found that its optical transmission (OT) and pulsed cathodoluminescence (PCL) spectra before irradiation do not differ from the spectra measured after irradiation with a dose of 45 Mrad within experimental error. The nature of the radiation resistance of rare-earth lutetium oxyorthosilicates (LFS) is discussed.
