摘要

一维纳米材料应用广泛，包括光电子、电子和电化学等。在本研究中，我们重点研究了 Ag-SnO 纳米纤维的结构、热和光学特性。Ag-SnO 纳米纤维是在不同的直流电压下利用电纺丝技术合成的。纤维的平均直径随着施加电压的增加而增大。X 射线衍射（XRD）分析显示形成了多晶的 Ag-SnO 纳米结构。在不同电压下观察到的结晶度变化不一致，在 14 kV 时观察到最大结晶度。光致发光（PL）表明存在锡间质。在 14 kV 下合成的 82 nm 纳米纤维具有最高的结晶质量和最低的缺陷浓度。这是将其用于传感器的先决条件。

Crystallization behavior of electro-spun Ag-SnO2 nanofibers through voltage-dependent alteration in Sn-interstitials

One-dimensional nanomaterials have a wide range of applications, including optoelectronics, electronic, and electro-chemical, among others. In this study, we focused on investigating the structural, thermal and optical properties of the Ag-SnO nanofibers. The Ag-SnO nanofibers, were synthesized by using electrospinning technique by applying different DC voltages. The average fiber diameter increased with the increase in applied voltages. The X-ray Diffraction (XRD) analysis, reveal the formation of polycrystalline Ag-SnO nanostructures. Inconsistent variation in crystallinity was observed at different voltages, with maximum crystallinity observed at 14 kV. The Photoluminescence (PL) indicates the presence of Sn-interstitials. The 82 nm synthesized nanofibers at 14 kV observed to have maximum crystalline quality and minimum defect concentration. A pre-requisite for their use in sensors.

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
