摘要：

Liquid phase epitaxy grown Lu(3)Al(5)O(12):Ce (LuAG:Ce) 20 mu m thick films and plate cut from the bulk Czochralski-grown LuAG:Ce crystal were prepared for comparison of photoelectron yield (PhY) and PhY dependence on shaping time (0.5-10 mu s). (241)Am (alpha particles) was used for excitation. At the 0.5 mu s shaping time, the best film shows comparable PhY with the bulk sample. PhY of bulk material increases noticeably more with shaping time than that of the films. Energy resolution of films is better. Influence of Pb(2+) contamination in the films (from the flux) and antisite Lu(Al) defect in bulk material is discussed. (c) 2008 American Institute of Physics.
