摘要: Trans-polyacetylene is evidenced by surface enhanced Raman scattering (SERS) in diamond films prepared hot filament assisted chemical vapor deposition from C${\mathrm{H}}_{4}$ and ${\mathrm{H}}_{2}$. The analysis of the spectra for different excitation energies shows that deposited trans-polyacetylene composed chains exhibiting short conjugation lengths. Together with polyacetylene, crystals nanometric dimension are both SERS high resolution transmission electron microscopy.
