Figure 5.

RT PL spectra of the annealed samples. Excitation was 365 nm, and it was obtained by HORIBA Nano Log equipped with a 450-W Xe lamp. The spectrum of sample 1 is magnified tenfold. The top left inset shows the integrated intensity of the samples. The left inset shows the PLE spectrum of annealed sample 3 monitored at 610 nm.
