| Abstract: | Copper oxide nanoparticles were prepared by laser ablation in aqueous solution.UV/Vis spectrum of the sample showed a characteristic absorption peak at 280 nm,which indicated the as-prepared nanoparticles were copper oxide.Atomic force microscopy(AFM) revealed that copper oxide nanoparticles have an elliptical shape of major axis size 30—50 nm and of thickness ~ 8 nm.Scanning electron microscope(SEM) showed that leaf-shaped aggregates appeared after deposition of copper oxide nanoparticles on an aluminum foil.A good surface enhancement effect of these aggregates was confirmed by Raman measurement.The SERS spectral evidences indicated that 4-mercaptopyridine adsorbed onto the copper oxide surface via the S atom with the protonated pyridine N atom.The molecular plane assumes a tilted orientation with respect to the copper oxide surface. |
