CuO nanowires film for sensors

摘要

CuO nanorods with the breadth of 60÷120 nm and the length up to 10 μm were synthesized using PVD method and thermal oxidation process. After PVD process a thick film composed from small nickel nanoparticles embedded in carbonaceous matrix was formed on the pure Cu surface. During the next step, the obtained film was heated with rising temperature under the air and annealed at different temperatures for 30 minutes. As a result a surface layer with a complex structure was formed. Microscopic examination revealed the complexity of the investigated structure. SEM, TEM, EDX and XRD investigations were performed. High resolution TEM studies revealed the subtle structure of CuO nanowires that was grown of the granular surface of CuO layer. CuO nanowires characterized by varied length and diameter.
