The formation and evolution of single-crystalline SnO2 nanobelts

摘要

Single-crystalline SnO_2 zigzag nanobelts and straight nanobelts with triangular tip were synthesized by a simple Tinwater reaction method. The product was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman scattering and micro-photoluminescence spectroscopy to obtain the structural and optical information. Why zigzag nanobelts and straight nanobelts can be formed respectively under the same experimental conditions? On the basis of TEM characterization and thermodynamic analysis, the formation mechanism of zigzag nanobelts and straight nanobelts were proposed respectively.
