摘要：
The origin of the visible luminescence from porous Si is argued in terms of a quantum well picture including a spectrum of Si-related states localized on the surface. We give evidence for the existence of such states and consider their role in the light emission process. We relate the observations of luminescence in porous Si to those for amorphous Si while pointing out characteristic differences.
