Figure 6From: Evolution of the sensitized Er3+ emission by silicon nanoclusters and luminescence centers in silicon-rich silicaEr-related PL spectra for the SROEr films with different Si concentrations. PL spectra of Er3+ for the 1,100°C-annealed SROEr films with different Si concentrations. All the films were excited by the 325-nm line of the He-Cd laser.Back to article page
