Abstract
AbstractSwift heavy ions induced effects on optical (color centers), structural and surface (electronic sputtering and morphology) modifications, in nano‐grains LiF thin films were studied by glancing angle X‐ray diffraction, optical absorption, photoluminescence and elastic recoil detection analysis techniques. Our results show that grain size and irradiation temperature play a crucial role in materials modifications as a function of fluence for the selected ion beam parameters. Also for the first time, lamellae formation was observed in LiF thin films after a high fluence irradiation of 5 × 1013 ions/cm2 at liquid nitrogen temperature with 120 MeV Ag ions irradiation under grazing incidence (∼10°).
