Abstract :
We investigated the room temperature electroluminescence of Er doped silicon diodes codoped with O or F as a function of dopant concentration and annealing conditions. Samples with Er concentrations of 5 × 1017 cm−3 and 1018 cm−3 show the most intense luminescence at λ = 1.54 μm. In case of F codoping the Er3+ peak intensity at 300 K is weak and there is a strong defect related peak at about the same wavelength.
