    Abstract

    Ordered arrays of Er-doped Si nanodots were fabricated by pulsed laser deposition using an anodic aluminum oxide (AAO) nanopore membrane. Er-doped Si (Si:Er) nanodots with an average diameter of 60-80 nm and a periodicity of 100 nm were uniformly assembled into hexagonally ordered nanopores of AAO membrane. Photoluminescence (PL) spectra taken from Si:Er nanodots showed an emission peak at 1.54 μm, which is due to intra- 4f shell transition (I 132 4 → I 152 4) of Er3+ ions. Postannealing of nanodot arrays up to 500 °C resulted in the enhancement of PL intensities without enlargement or aggregation of the nanodots.
