Heteroe-Pitaxial Growth and Optical Properties of SnO2 Nanowires on ZnS Nanobelts
Abstract:
The authors present the results of hetero-epitaxial growth of ultrafine SnO2 nanowires on ZnS nanobelt substrates by a simple thermal evaporation method. ZnS/SnO2 hetero-nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS), transmission electron microscopy (TEM) to obtain the morphology and structural information. Comparing with ZnS nanobelts and SnO2 nanowires respectively, the optical properties of ZnS/SnO2 hetero-nanostructures are studied by Raman scattering and photoluminescence (PL) spectroscopy at room temperature.
