Photoluminescence and Photoluminescence Excitation of Si Aerogels Prepared by Supercritical Drying
-
Abstract
Si aerogel, the porous silicon with ultra high porosity, has been prepared by the technique of anodization followed by supercritical drying. Its photoluminescence, photoluminescence excitation and morphological features exhibit novel characteristics from those of the conventionally anodized porous silicon. We observed the differences between the Si aerogels made from <100> and <111> crystalline Si.
