dc.description.abstract© 2019 SPIE. The luminescent and structural properties of GeO x thin films and GeO/SiO 2 multilayer heterostructures, irradiated with 167 MeV Xe ions with fluencies up to 10 13 cm -2 , were studied. We report strong photoluminescence in visible range at room temperature, which is most probably due to Ge-related defect-induced radiative transitions. And infrared luminescence bands (from ∼0.8 eV to ∼1.2 eV) were observed in as-deposited and irradiated structures, which can be related to defects or defects complexes in Ge x Si y O 2 glass and partially in Si substrate. It was shown that swift heavy ion irradiation does not lead to the expected phase separation of germanium suboxide into germanium nanoclusters and GeO 2 , but causes the intermixing of GeO/SiO 2 layers with the formation of Ge-O-Si bonds.
