We here report the growth and structural characterization of Sb-doped SnO2 nanowires synthesized by Vapor Liquid-Solid technique using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray Photoelectron Spectroscopy (XPS) and Raman spectroscopy. Both X-ray diffraction and Raman spectroscopy exhibited typical features of the rutile phase of SnO2 nanowires for all samples. The analysis of XPS confirmed the Sb doping effectiveness. In addition, Raman spectra revealed inactive modes (242 and 284 cm-1) attributed to local structural disorder caused by the incorporation of the dopant into the SnO2 lattice and leading to the breakdown of the Raman selection rules.

拉曼光谱和XPS光谱探测VLS合成SnO 2纳米线的Sb掺杂

我们在这里报告通过使用X射线衍射,扫描电子显微镜,能量色散X射线光谱,X射线光电子能谱(XPS)和拉曼光谱的蒸气液固技术合成的掺Sb的SnO 2纳米线的生长和结构表征光谱学。对于所有样品,X射线衍射和拉曼光谱均显示出SnO 2纳米线的金红石相的典型特征。XPS的分析证实了Sb掺杂的有效性。另外,拉曼光谱显示出非活性模式(242和284cm -1),其归因于由于将掺杂剂掺入SnO 2晶格中引起的局部结构紊乱并导致拉曼选择规则的破坏。
