Preliminary studies of optical transmission, luminescence, light output, and decay time have been carried out. It was found that after annealing of LuYAG:Ce and YAG:Ce,Ca crystals, their light output increases from 1.5 to 2.5 times. For crystals after annealing, a decrease in the decay time is observed. For example, for YAG:Ce,Ca with a Ce/Ca concentration ratio of 0.3/0.6%, the decay time before annealing was 202 ns, and after annealing it decreased to 63 ns. The optimal crystals for creating fast composite scintillators at the next stage of work are YAG:Ce,Ca (after annealing) and LuAG:Ce crystals. Product Description popup.authors Kofanov Denys О.
