A detailed investigation of the excitation mechanisms of the 4I13/2-4I15/2 intra-4f-shell luminescence of Er3+ ions near 1.5 μm in silicon-rich silicon oxide (SRSO) is reported. SRSO:Er was produced by high dose implantation of Si+ ions into SiO2 layers grown on silicon, followed by Er+ implantation at an energy of 800 keV. Samples were thermally annealed up to 1100oC to create different types of defects and Si-nanocrystals (nc-Si). Photoluminescence excitation (PLE) spectra were obtained using optical parametric oscillator (OPO) and Ti:Sapphire laser in the range 420-680 and 720-830 nm, respectively.
