The luminescence response of samples of ZnS:Ag and Zn2SiO4:Mn to bombardment with various ions was determined as a function of the ion energy. For ZnS:Ag, within the range of ion energies studied (E < 25 kev.), the luminescence response, L, is related to the ion energy, E, according to [Formula: see text]. E0 is a threshold energy which is not a very sensitive function of ion mass. For Zn2SiO4:Mn no threshold energy was observed except in the case of Li7+ ions, the lightest ions used with this phosphor. The experimental results for ZnS:Ag appear to be consistent with a theory in which it is assumed that the bombarding particles penetrate the phosphor as neutral atoms and produce luminescence by electronic excitation of the lattice atoms due to small impact parameter collisions.
