We investigated scintillation decay times at different excitation γ-ray energies for commercial luminescent materials such as Ce:LaBr3, Eu:SrI2, Ce:LYSO [(Y,Lu)2SiO5], and Ce:GAGG [Gd3(Al,Ga)5O12]. Ce:LaBr3 and Eu:SrI2 did not show energy dependence, whereas Ce:LYSO and Ce:GAGG exhibited different decay curves at different excitation energies. In these materials, the energy dependence of decay correlated with the nonproportionality of scintillation light yield.
