We have characterized the ionoluminescent response of several phosphor powder materials when
irradiated with ions of different masses H+ ,He+ ,Ar+ accelerated to keV energies. In particular, we
have determined the absolute luminosity in terms of the number of photons per incident ion emitted
by luminescent screens of Y2O2S:Tb P45, Y3Al5O12 :Ce P46, Y2SiO5 :Ce P47, Y2O3 :Eu
P56, and SrGa2S4 :Eu TG-green. Their ionoluminescence has been studied as a function of ion beam energy and current and ion fluency. The energy trend and mass dependence of selected experimental results are compared relative to stopping and range of ions in matter SRIM code predictions.Ministerio de Educación y Ciencia FTN2003-090
