Abstract

We present a photoluminescence study of erbium implanted into porous silicon (Er:PSi) with two different Si porosities, a) Er:PSi with a purple appearance and b) with a green-yellow appearance. Er was implanted with a dose of 1×10¹⁵ Er/cm² at 380 keV and annealed at 650 °C for 30 minutes. Room-temperature 1.54 μm Er³⁺ emission was observed from both samples. The emission from purple Er:PSi was four times stronger than that from green-yellow Er:PSi. In contrast, visible luminescence from green-yellow Er:PSi was found to be stronger than that from purple Er:PSi. Temperature quenching and power dependence was investigated to elucidate the excitation mechanisms of Er³⁺ in porous silicon. The results support a correlation between nanostructures of porous Si and 1.54 μm Er³⁺ luminescence.
