ITPL of the SROEr-I matrix and Er3+ions, and HRTEM image of the SROEr-I films. The evolution of SROEr-I matrix-related ITPL (left-hand scale) and that of Er-related ITPL (right-hand scale) with annealing temperatures. All the films were excited by the 325-nm line of the He-Cd laser. The inset shows the HRTEM image of coalescent Si NCs in the 1,150°C-annealed SROEr-I film.
