Matrix-related PL spectra of the SROEr-I films annealed at different temperatures. PL spectra of the SROEr-I matrix annealed at different temperatures: (a) as-deposited, (b) 700°C, (c) 900°C, (d) 1,000°C, and (e) 1,150°C. The experimental data are denoted by black lines, and the fitting data of the general and the divided peaks are denoted by the red and green lines, respectively. All the films were excited by the 325-nm line of the He-Cd laser.
