![عکس صفحه اول مقاله: Synthesis and characterization of amorphous silicon oxide nanowires embedded with Ni nanoparticles Synthesis and characterization of amorphous silicon oxide nanowires embedded with Ni nanoparticles](/preview/png/1523189.png)
The growth of silicon oxide nanowires (SiOxNWs) was obtained by thermal process of nickel (Ni) nanoparticles (NPs) deposited on silicon (Si) wafer in mixed gases of nitrogen (N2) and hydrogen (H2). TEM analysis showed that SiOxNWs had diameters ranging from 100 to 200 nm with lengths extending up to a few μm and their structure was amorphous. SiOxNWs were grown by the reaction between Ni NPs and Si wafer and Ni NPs acted as catalysts. Ni silicides (NixSi) were also formed inside the wafer by Ni diffusion into Si wafer.
► Silicon oxide nanowires were obtained by thermal treatment of nickel nanoparticles.
► The nanowires showed a blue light emission at ∼450 nm
► Nickel nanoparticles acted as catalysts.
► The nanowires had amorphous structure.
