Abstract

The aim of this work is to study the changes produced in gold after laser produced ion irradiation. A pulsed Nd: YAG laser (Pulse duration 9-12 ns, power 1.1MW) is used to produce Tin ions which were irradiated on gold. XRD pattern of gold are taken before and after ion irradiation. A comparison of these patterns reveals that the intensity of diffraction lines in XRD pattern changed after laser produced ion irradiation owing to displacement (knocked in and knocked out) of gold atoms. SEM micrographs of tin ions irradiated Gold sample not only provide evidences of sputtering and crater formation but also indicate re-deposition of sputtered material. Thermal spikes are also observed in SEM micrograph.
