Abstract
Local spots on the surface of ZnS:Ag phosphor samples were deteriorated by a large number (~5 × 1013 ions per cm2) of low-energy ions. In this manner thin films which did not luminesce under ion bombardment were prepared. These phosphor samples were scanned across energetic ion beams with sufficient energy to traverse the thin phosphor films. By comparing the luminescent response to this ion excitation in the damaged and undamaged portions of the phosphor surface the total average energy losses of 1H, 4He, 14N, 40Ar, and 84Kr, in passing through the films, were determined. It was found that the energy losses for the heavier projectiles, when compared with the energy loss for hydrogen, are appreciably smaller than those predicted by the Lindhard and Scharff theory.Keywords
