## Description

- description: " 　We have found that tungsten oxide nanorods have a very large enhancement
    effect on Raman scattering. The nanorods with adsorbed 12CO and 13CO at the ratio
    of 1:1 were dispersed on a Si substrate and Raman mapping was performed. The Raman
    images of 12CO and 13CO were completely different, indicating that a very small
    number of molecules at the single-molecule level were observed. We also confirmed
    the characteristic blinking phenomenon when single-molecule detection was performed.
    The very large enhancement effect of Raman scattering can be attributed to the
    {001}CS structure of the tungsten oxide nanorods. It was confirmed from the DFT
    calculation results that the {001}CS structure exhibits two-dimensional electrical
    conduction properties."
