Synthesis, morphologies and Raman-scattering spectra of crystalline stannic oxide nanowires

摘要: SnO2 nanowires were synthesized using a direct gas reaction route and characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), selected-area (SAED), high-resolution transmission (HRTEM) Raman-scattering spectroscopy. XRD, SEM, SAED HRTEM indicated that the products tetragonal with diameters of 10–50 nm. The single crystal solid inside. Dendritic observed for first time. Three vibrational modes in Raman spectra samples.
