An Er-doped porous silicon (PSi) was used to obtain a strong enhancement of the Er3+ -related 1.54 μm emission. The measurement of the energy transfer and the Auger deexcitation between carriers in Si crystallites of preoxidized PSi and Er3+ were performed. It was found that a thin SiO2 interlayer was also effective at suppressing the phonon-assisted energy backtransfer at high temperatures.
