Abstract

Polyol synthesis of thin silver nanowires has been studied and their suitability for the formation of transparent electrodes has been shown. The influence of stepwise heating of the reaction system on the position and shape of the absorption band associated with the surface plasmon resonance of the formed silver nanostructures has been determined. Using X-ray powder diffraction analysis, it has been found that the material does not contain crystalline impurities and has a face-centered cubic lattice. According to the scanning and transmission electron microscopy data, the main fraction is represented by elongated nanostructures with 10–15 μm length (however, there are also structures with length up to 20 μm) characteristic for silver nanowires of the arc-shaped type. It is shown that the Ag nanowires obtained are quite thin (diameter is about 35–45 nm). In addition, some amount of microrods of 1–3 µm length is observed in the composition of the material, the diameter of which grows from 70 to 150 nm with decreasing length. In smaller quantities there is also an admixture of zero-dimensional particles, which are polyhedrons of various complexity. Atomic force microscopy has been used to study the surface of the film based on the obtained silver nanowires and the diameter of individual nanowire has been estimated. The optical properties and surface resistivity of the films based on the obtained silver nanowires have been examined. It has been found that the increase in transmittance at 550 nm from 73.9 to 90.3% is accompanied by an increase in the resistance value from 25 to 146 Ω/sq.

多元醇合成银纳米线及其在透明电极制造中的应用

摘要研究了薄银纳米线的多元醇合成，并证明了它们在形成透明电极方面的适用性。研究确定了反应体系逐步加热对与所形成的银纳米结构的表面等离子共振有关的吸收带的位置和形状的影响。通过 X 射线粉末衍射分析发现，该材料不含结晶杂质，具有面心立方晶格。根据扫描和透射电子显微镜数据，主要部分是长度为 10-15 μm 的细长纳米结构（但也有长度达 20 μm 的结构），具有弧形银纳米线的特征。结果表明，获得的银纳米线非常细（直径约为 35-45 纳米）。此外，在材料成分中还观察到一些长度为 1-3 µm 的微晶，其直径随着长度的减小从 70 纳米到 150 纳米不等。此外，还有少量的零维颗粒，它们是各种复杂程度的多面体。我们使用原子力显微镜研究了以获得的银纳米线为基础的薄膜表面，并估算了单根纳米线的直径。研究了基于所获得的银纳米线的薄膜的光学特性和表面电阻率。研究发现，在 550 纳米波长处的透射率从 73.9% 增加到 90.3%，同时电阻值也从 25Ω/sq 增加到 146Ω/sq。
