(color online) (a) Normalized RT PL spectra of G1 and G2. The emission intensities of G1 and G2 were normalized at the NBE region in order to compare the relative intensities of the peaks near 650 nm. (b) RT PL spectra of samples G1, G1 after annealing (G1 AN), and Z. An energy level diagram for DLE is shown in the inset.
