摘      要：Si aerogel,the porous silicon with ultra high porosity,has been prepared by the technique of anodization followed by supercritical *** photoluminescence,photoluminescence excitation and morphological features exhibit novel characteristics from those of the conventionally anodized porous *** observed the differences between the Si aerogels made&om(100)and(111)crystalline Si.
