摘要：
Photoluminescence spectroscopy, Fourier transform infrared spectroscopy, X-ray reflectometry and high resolution electron microscopy have been used to interpret the photoluminescence properties of annealed (3/19 nm) Si/SiO2 multilayers grown by reactive magnetron sputtering. The multilayers show an emission in the visible and near-infrared range after heat treatment from 900degreesC which tends to decrease from 1200degreesC. Three different origins for the photoluminescence activity have been found. An anneal temperature of 1200degreesC is necessary to optimise the silicon crystallisation within the silicon sublayers.
