چکیده انگلیسی
The 2 inch size Li 0.15 and 1.35Â mol% co-doped Ce:Gd3Al2Ga3O12 single crystals were prepared by the Czochralski (Cz) method. Absorption and luminescence spectra were measured together with several other scintillation characteristics, namely the scintillation decay and light yield to reveal the effect of Li co-doping. Ce4+ CT absorption below 350Â nm is clearly enhanced by Li co-doping as same as divalent ions co-doping. By 1.35Â at.% Li co-doping, light yield was decrease to 88% of the Ce: GAGG standard and decay time was accelerated to 34.3ns 21.0%, 84.6ns 68.7%, 480ns 10.3%. The timing resolution measurement for a pair of 3Â ÃÂ 3Â ÃÂ 3mm3 size Li,Ce:GAGG scintillator crystals was performed using Si-PMs and the timing resolution of the 1.35Â at.% Li co-doped Ce:GAGG was 218ps.
