Effect of the Pr3+Gd3+ energy transfer in multicomponent garnet single crystal scintillators
Result description
Luminescence processes in the undoped and Pr3+-doped (Gd,RE)3(Ga,Al)5O12, RE=Lu,Y, multicomponent garnets are studied by the time-resolved photoluminescence spectroscopy. Energy transfer processes between Pr3+ and Gd3+ causing significant deterioration of the scintillation performance are considered in detail. As it is shown in current work, an overlap of the 5d1-3H4 emission transition of Pr3+ and 8S-6Px absorption transition of Gd3+ results in unwanted depletion of Pr3+ 5d1 excited state and is further intensified by the concentration quenching in the Gd3+-sublattice. This process explains a drastic decrease of light yield in Pr3+-doped Gd3+-containing multicomponent garnets observed in a previous work.
