Experimental demonstration of nanoCARS: coherent anti-Stokes Raman scattering in mesoporous silica aerogels infiltrated with condensed- and gas-phase Raman-active materials

Coherent anti‐Stokes Raman scattering (CARS) is shown to allow the reliable detection of Raman‐active modes of gas‐phase molecular nitrogen, and also toluene molecules in the condensed and gas phases infiltrated into mesoporous silica aerogels. We experimentally demonstrate a nanoscale extension of...

Description
Summary:Coherent anti‐Stokes Raman scattering (CARS) is shown to allow the reliable detection of Raman‐active modes of gas‐phase molecular nitrogen, and also toluene molecules in the condensed and gas phases infiltrated into mesoporous silica aerogels. We experimentally demonstrate a nanoscale extension of CARS methodology, referred to as nanoCARS, adapting CARS for local probing of nanostructures and nanocomposite materials, and also for the sensing of Raman‐active species in the liquid and gas phases in a nanocomposite host.
