Abstract
The structural transformations induced in Gd2O3 and Eu2O3 irradiated with high‐energy ions (94‐MeV Pb and 1042‐MeV Xe), where ionization processes (electronic stopping) dominate the ion slowing‐down, have been studied via the combination of XRD and Raman experiments. Irradiation induces a cubic‐to‐monoclinic phase transformation; the radiation‐induced monoclinic phase shows strong preferential orientation. This structural modification is accompanied by changes in the photoluminescence properties of sesquioxides. The results show that swift heavy ion irradiation is a powerful tool to control the properties of oxides at the nanoscale.
