Nanostructured CuO samples were irradiated with He&sup(+) ions at doses of 3.13 × 10&sup(13)–3.38 × 10&sup(16) particles/cm&sup(2) to probe defect dynamics and lattice recovery. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, positron annihilation lifetime spectroscopy (PALS), and Doppler broadening spectroscopy (DBS) revealed that short irradiation promotes lattice recovery, while prolonged exposure induces a competition between recovery, Cu vacancy (V&sub(Cu)) formation, and complex vacancy cluster (V&sup(−)&sub(C)u − V&sup(+)&sub(O)) evolution. Elevated positron lifetimes (*t&sub(2)) highlight defective, isolated nanorod surfaces, with a defective surface region averaging *r ≈ 1.5 nm. These results demonstrate the dual role of irradiation in defect creation and lattice healing, offering insights into CuO stability under radiation environments.
