Due to their high porosity, high transparency in the visible, and weak scattering, silica aerogels are shown to provide an ideal host for Raman-active gases and liquids, detected and analyzed by coherent anti-Stokes Raman scattering, allowing the creation of gas- and condensed-phase sensors of chemical and biological species, including sensors of pollutants and aerosols.en0009-261420041-314ElsevierPhysikChemieJournal Article10.1016/j.cplett.2004.05.114Other
