Abstract

Photoluminescence (PL) properties of Er-doped structures of Si nanocrystals in SiO2 matrix are investigated at different temperatures and excitation intensities. Er-doped structures exhibit the PL line at 1.5 μm, which results from the radiative transitions in Er3+ ions excited by the energy transfer from Si nanocrystals. The PL yield and lifetime are found to be dependent on the nanocrystal size, temperature, and excitation intensity. The experimental results are explained by a strong coupling between excitons confined in Si nanocrystals and Er3+ ions in surrounding SiO 2.
