Název v původním jazyce

Temperature dependence of photoluminescence kinetics, scintillation properties, and coincidence time resolution of Mo co-doped Y1.5Gd1.5Al2Ga3O12:Ce (Mo=0, 300, 600 ppm) multicomponent garnet crystals

Popis výsledku v původním jazyce

Luminescence and scintillation properties of Mo co-doped Y1.5Gd1.5Al2Ga3O12:Ce,Mo (Mo = 0, 300, 600 ppm) multicomponent garnet crystals grown by the micro-pulling-down method were investigated. To investigate temperature stability, temperature dependence of photoluminescence decay time was measured from 77 to 487 K and thermal activation energy was determined. Y1.5Gd1.5Al2Ga3O12:Ce,Mo (300, 600 ppm) samples showed faster scintillation decay time with a similar LY value compared to Mo-free Y1.5Gd1.5Al2Ga3O12:Ce one. Y1.5Gd1.5Al2Ga3O12:Ce,Mo (600 ppm) showed a light yield value of 34,300 photons/MeV along with fast scintillation decay times of 45.2 ns (55 %) +153 ns (45 %) and time resolution of 313 ps. Radioluminescence and afterglow signal were also measured at RT and discussed.
