摘要：

In this paper we report the Raman spectra of polystyrene films irradiated with 240 keV Ar+ ions at fluences between 1015 and 4 × 1016 cm-2. The presence of two broad bands ID, and IG at 1380 and 1560 cm-1 clearly indicates that ion bombardment induces a transition from the original molecular solid to hydrogenated amorphous carbon. Computer analysis of these spectra shows that the ratio ID IG increases with ion fluence till a saturation value of about 2. We explain this behaviour with the formation and growth of ordered clusters. © 1990.
