Figure 1From: Energy transfer from luminescent centers to Er3+ in erbium-doped silicon-rich oxide filmsPL spectra of SROEr films with different annealing temperatures. PL spectra of (a) the A. D. SROEr film and the SROEr films annealed at (b) 700°C, (c) 900°C, and (d) 1,150°C in N2 ambience for 30 min. The experimental data is denoted by black lines, the fitting data of the general and the divided peaks are denoted by the red and green lines, respectively.Back to article page
