摘要
It is found that the photoluminescence spectrum of a porous Si sample changes from one peak to two peaks with decreasing temperatures to less than 131 K. The spectrum change could be interpreted in terms of the reabsorption of the luminescence by absorption centers stable at low temperatures in porous Si. This suggests that some of the anomalous temperature dependences of the luminescence intensity can be explained by the reabsorption.
