ZnO:Ni nanowires have been fabricated through high temperature vapor-solid deposition process. The morphology of the as-prepared samples was characterized by scanning electron microscopy. The room temperature Raman spectrum exhibited the presence of lattice defects in the system. The vibration modes of undoped ZnO and additional modes have been observed in the Raman spectra of Ni-doped ZnO nanowires...
Metal/semiconductor nanostructure materials have been used as surface-enhanced Raman scattering (SERS) active substrates and have drawn much attention due to their widespread applications in both optical and electronics fields. Here, we report a simple approach to prepare a large-scale ZnO/SiO2/Ag nanoparticles (NPs) by the reduction of [Ag(NH3)2]+ with the reducing agent SnCl2·H2O in aqueous solution...
