Abstract:
It is found that Er could only be deposited on a Si cathode by electrolysis of near neutral ErCl 3 electrolyte with a large current density. The deposited Er hydrolytic layer reacts with Si at 1200 °C to form the activated Er centers that emit a 1.533 μm photoluminescence peak at room temperature. By applying this process to porous Si, an apparent doping concentration of Er larger than 10 19 /cm 3 in the whole porous Si layer and a strong PL intensity with little temperature quenching are achieved.
