Abstract
The discovery of visible luminescence from porous silicon has generated significant interest in view of the fact that bulk silicon does not emit light in the visible part of the spectrum. This material differs from bulk silicon in one important way: it consists of interconnected silicon structures that in some cases are on the order of several nanometers. having a very large surface-to-volume ratio. Thus, in a material such as this, both the effect of particle size and surfaces must be examined in order to determine the optical behavior of this system.
