| Abstract: | ZnO/Ag nanocomposites were synthesized by reducing silver ions on the ZnO nanocrystal surface,and the optical properties of the nanocomposites were studied.The size distribution and morphology of ZnO/Ag nanocomposites were characterized by TEM and XRD.The UV-vis absorption spectra and photoluminescence of ZnO/Ag nanocomposites showed that the electron transfer occurred between ZnO and Ag.Furthermore,surface enhanced resonant Raman scattering of the ZnO/Ag nanocomposites was observed with excitation of 325 n... |
