Spectra of surface-enhanced Raman scattering of nanocluster NaXe

The spectral characteristics of the surface-enhanced Raman scattering (SERS) of nanocluster NaXe in NaCl at room temperature, were analyzed. The SERS spectra of NaCl samples containing NaXe nanoclusters are measured by a Reinshaw micro spectrometer system 1000. It was observed that the peak values of SERS, produced by the dissociation of nanocluster NaXe, were very close to the critical point phonon frequencies of NaCl lattice in the second-order Raman scattering. The results show that the lower concentration of NaXe nanoclusters, which displays light blue color, has the lower intensity of SERS.
