Figure 7.

Photoluminescence spectra of as-grown and RTA-treated samples at different temperatures (a). Gaussian fittings of PL spectrum for different samples (b-f). Black curves are the experimental data, while the green and red curves indicate the fittings to the experimental data. The three peaks and peak sum are shown by green and red curves, respectively.
