In this study, we investigate the effects of Ho3+ codoping on the luminescence and scintillation properties of GGAG:Ce, with a particular focus on timing properties and scintillator efficiency. The research reveals that Ho3+ codoping and subsequent resonant energy transfer from Ce3+ to Ho3+ can significantly reduce the 5d1 excited state decay time of Ce3+ and shorten scintillation pulses of GGAG:Ce registered by using hotomultipliers, although this reduces scintillator efficiency as well. The study presents a detailed analysis of the loss of scintillator efficiency due to Ho3+ codoping, identifying the most significant loss pathways and estimating their impact. The findings suggest that Ho3+ codoping is an effective method for accelerating the scintillation response of GGAG:Ce.
