The luminescence of KBr, YAG:Ce, CaF2:Eu and CsI:Tl scintillators induced with H2 + ion beams in the energy range of 600-2150 keV/u has been systematically measured as a function of irradiation time. The measurements showed that the luminescence of CsI:Tl and YAG:Ce remained constant within the 1-hour continuous irradiation. An initial fast drop of the luminescence on CaF2:Eu was observed but the light output eventually approached a stable state under constant ion bombardment. We also observed that the light output of KBr initially increased and then degraded gradually with further irradiation. The CsI:Tl screen produced the highest scintillation yield and KBr the lowest.
