Figure 3From: Modification of the optical and structural properties of ZnO nanowires by low-energy Ar+ ion sputteringNormalized CL spectra collected on individual NWs. Unirradiated (NR) and irradiated areas with fluences of 1.5 × 1016 cm−2 and 1017 cm−2. An increase of the NBE emission with respect to the visible band as the irradiation fluence increases is observed (see the inset). Gaussian deconvolution bands are also shown.Back to article page
