Abstract
Single crystal cerium doped yttrium aluminum garnet boules (Ce:YAG, 0.25-4.0 at. % Ce) were grown under similar conditions by the Czochralski method. Scintillation, photoluminescence, and lifetime measurements demonstrate reduced UV defect emission and increased visible emission as cerium doping increases, resulting from greater competitiveness of cerium luminescence centers among defect centers. Photodiode energy resolutions improved significantly, where 2.0 at. % Ce:YAG displayed 8.9% (6.14% with noise reduction) at 662 keV without post-processing. Therefore large, highly doped, as grown Ce:YAG, can achieve resolutions on cost effective photodiodes that are generally observed only with photo multiplier tubes and avalanche photodiodes at low doping levels.
