Optical properties and gamma-ray response of Czochralski grown Pr:Lu3Al5O12 scintillating garnet crystals with different Pr content

Scintillation response of Lu3Al5O12:Pr3+ single crystal scintillators

“…This fact, together with the results in Refs. [14][15][16], agrees with the conclusions of Ogino et al [11] that the light yield of LuAG:Pr first increases with concentration, peaks at about 0.22-0.24% Pr, and decreases. Table 1 summarizes the values of photoelectron yield and energy resolution (at 662 keV) for the studied crystals coupled to the XP5200B PMT.…”

“…These properties make LuAG:Pr a very promising scintillator for a number of applications. It was found that the light yield of LuAG:Pr increases with Pr concentration from 0.1 to 0.22 mol%, peaks at about 0.22-0.24 mol%, and then decreases [11,15]. The decrease of the light yield with increasing Pr concentration from 1.5 to 10 mol% was also reported [16].…”

“…2, a, b, кривая 1) и детально описанные в работе [9]. Максимумы УФ полос поглощения 240 и 285 nm имеют величину оптической плотности выше 2.7 (предел шкалы прибора) при толщине образцов 1 mm, поэтому невозможно оценить изменение оптической плотности после облучения и термообработки.…”

“…The photoelectron yield of the used BGO was evaluated as 4963 ± 500 phelMe V by using a Si APD compared with a 55Fe 5.9 keY X-ray direct irradiation to Si which generated 1640 electron-hole pairs. The detailed description of our experimental setup for Si-APD readout can be found in some literatures [17]- [ 19].…”
