The authors report the growth of layered graphene on carbon fiber surfaces by DC-PCVD. The morphology and microstructure of the as-grown samples are characterised using SEM and HRTEM methods. Raman spectra and field emission characteristics are also discussed.
Iron films with different thickness were prepared on glass substrate by DC magnetron sputtering. Arrays of α-Fe2O3 nanowires and nanosheets were grown on iron films by thermal oxidation. The morphology and structure of the prepared α-Fe2O3 nanostructures were characterized by SEM, XRD, XPS, Raman and HRTEM. Field emission properties including I-V characteristics, emission uniformity and stability...
Monodisperse CeO2 nanospheres were synthesized by hydrothermal treatment of Ce(NO3)3??6H2O using polyvinylpyrrolidone (PVP) as a surfactant. The structure and morphology of the products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM) and Raman spectroscopy. The optical properties of the nanospheres were determined...
The alpha-MoO3, h-MoO3 and Mo4O11 oxides are formed by low-temperature chemical synthesis from water-based solutions by different precipators. Phase purity and high crystallinity of final products are confirmed with XRD and TEM analysis. Spectral properties of molybdenum oxide nanocrystals are measured with IR and Raman spectroscopies. Lo-temperature precipitation from water-based solutions can be...
