Abstract :
The present paper concerns the study of nanostructures formed by immersion deposition of silver on porous silicon at different modes for their application in surface enhanced Raman spectroscopy. Porous silicon has been fabricated by anodization of monocrystalline silicon in water solution of isopropanol and hydrofluoric acid. Reflectance spectra of the obtained structures of silver/porous silicon have been studied. It has been revealed that the highest level of Raman signal requires using laser with wavelength of 400 - 450 nm.
