Figure 6From: FTIR and Raman Spectroscopy of Carbon Nanoparticles in SiO2, ZnO and NiO MatricesRaman spectroscopy on difference spots of the C–ZnO sample. The G peak has been re-drawn to show the asymmetry which is an indication of the phonon confinement in nanoclusters of carbon within the ZnO matrixBack to article page
