Zinc oxide (ZnO) nanoparticles were coated on the surface of multi walled carbon nanotubes (MWCNTs) to improve the field emission characteristic of MWCNTs. The synthesis of MWCNTs was made by chemical vapor deposition (CVD). RF sputtering was used to prepare MWCNTs/ZnO nanocomposite. The as-prepared nanocomposites were identified by electron microscopes (transmission and scanning), Raman spectroscopy...
Flower-like zinc oxide (ZnO) nanostructures with hexagonal crown were synthesized on a Si substrate by direct thermal evaporation of zinc power at a low temperature of 600 °C and atmospheric pressure. Field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Raman spectroscopy and photoluminescence were applied to study the structural characteristics and optical...
