Tailoring scintillation and luminescence through Co-doping engineering: A comparative study of Ce,Tb Co-doped YAGG and GAGG garnet crystals
Original language description
The development of scintillators with co-doping mechanisms has received significant attention due to the resulting enhancements in luminescence and scintillation properties. Scintillators such as Ce-doped (Gd,Tb)3(Al,Ga)5O12 have been recognized for their improved performance, attributed to the effective energy transfer between Ce3+ and Tb3+ ions. Nevertheless, the presence of Gd3+ introduced complexities, as its absorption lines strongly overlap with those of Tb3+, thus masking the details of mechanisms of the Tb3+↔Ce3+ energy transfer. This study endeavored to elucidate this mechanism by comparing the luminescence characteristics of Ce,Tb codoped Y3Al2Ga3O12 (YAGG) and Gd3A2Ga3O12 (GAGG) single crystals. Through detailed photoluminescence spectral analysis, it was discerned that GAGG exhibited a more robust Tb3+↔Ce3+ energy transfer, as evidenced by a marked extension in the decay time of Ce3+ luminescence. Furthermore, GAGG demonstrated superior integrated radioluminescence intensity across all compositions which is a result of efficient energy transfer from Gd3+ to the luminescence centers. Additionally, comparative thermally stimulated luminescence glow curves, revealed distinctive spectral features between YAGG and GAGG, underscoring the complexity of their luminescence mechanisms. This comparative study not only augmented our comprehension of the intricate energy transfer processes in Ce, Tb co-doped garnet scintillators but also underscored the potential for tailored scintillator development through strategic ion co-doping.
