Abstract

ZnO crystals were irradiated with high energy electrons (1MeV). The main defects created were analyzed by cathodoluminescence (CL) spectroscopy. The main effects of irradiation on the CL spectrum were the partial quenching of the emission, the shift of the visible luminescence to the yellow, and the observation of an additional band and its phonon replicas at ∼3.32 eV. Zinc vacancy related defects are postulated as responsible for the changes induced in the spectrum.
