摘要：

We report on the effect of annealing treatment on the structural and optical properties of Er-doped Al2O3 thin films elaborated by atomic layer deposition. The properties of the films were studied using ellipsometry and Fourier-transform infrared (FTIR) spectroscopies, cathodoluminescence (CL) versus annealing temperature varied in the 650-1100 degrees C range. Spatial location and diffusion of chemical species were investigated at the atomic scale by atom probe tomography (APT). The CL measurements evidence Er3+ light emission over the visible-infrared spectral range. The CL spectra evolution showed non-monotonic variation with annealing temperature and a CL quenching occurring at 1000 degrees C. The CL signal evolution as a function of the annealing treatment is discussed regarding to the evolution of structural properties.
