Method, structure, and apparatus for Raman spectroscopy

Image Number 3 for United States Patent #7599056.

Disclosed herein are a Raman spectroscopy structure comprising a porous material substrate, and a method of performing Raman spectroscopy of a sample disposed adjacent to the structure comprising the porous material substrate. Generally, the substrate includes one or more layers of a porous material such as porous silicon, porous polysilicon, porous ceramics, porous silica, porous alumina, porous silicon-germanium, porous germanium, porous gallium arsenide, porous gallium phosphide, porous zinc oxide, and porous silicon carbide. It has been discovered that such a substrate material, when excited with near-infrared light, does not exhibit undesired background fluorescence characteristic of other known Raman spectroscopy substrates.
