Effect of ^ Co-Doping on the Scintillation Kinetics of Ce Doped

The temperature dependence of scintillation decay and rise time was measured for GGAG:Ce and Ca-codoped GGAG:Ce crystals in the temperature range of 10 K to 400 K. The decay and rise times were found to increase with decreasing temperature in the case of GGAG:Ce crystals, while Ca codoping modifies...

Zusammenfassung:The temperature dependence of scintillation decay and rise time was measured for GGAG:Ce and Ca-codoped GGAG:Ce crystals in the temperature range of 10 K to 400 K. The decay and rise times were found to increase with decreasing temperature in the case of GGAG:Ce crystals, while Ca codoping modifies the kinetics such that decay and rise times are constant with the change in temperature. In order to obtain a better understanding of the role of trap centers in the temperature dependence of scintillation kinetics, spectrally resolved thermoluminescence (TL) properties were also studied for these crystals.
