Figure 2

μPL spectra. Unirradiated (NR) and irradiated areas with fluences of 1.5 × 1016 cm−2 and 1017 cm−2. The spectra, normalized to the band-to-band recombination, show the diminution of the visible band intensity as the irradiation energy increases. Gaussian deconvolution bands are also shown. The inset shows the intensity ratio INBE/IDLE as a function of the irradiation fluence.
