摘要
利用溶剂热法,乙二醇为溶剂和还原剂,PVP为表面活性剂,硝酸银为银源,讨论硫化钠浓度对银纳米线尺度的影响。用SEM、XRD和紫外光谱对银纳米线及其薄膜的形貌和透过率进行分析。实验表明,银纳米线薄膜的光透过率与其直径大小有重要关系。当Na2S浓度为0.4 mol/L时,银纳米线的尺度最均匀,平均直径为90 nm,以此制备的薄膜透过率平均值大于85%,且在330 nm波长处有最大值89%,高于平均直径45 nm组的透过率,而平均直径200 nm组的透过率仅为65%。
The effect of sodium sulfide concentration on the scale of silver nanowires is discussed by solvothermal method. Ethylene glycol is a solvent and reducing agent, PVP is a surface active agent, and silver nitrate is the silver source. The morphology of the silver nanowires and transmittance of their films are analyzed by SEM, XRD and UV spectra. Thus, the experimental results show that the optical transmittance of the silver nanowire thin film has an important relation with its diameter. When the Na2 S concentration is 0.4 mol/L, the dimensions of silver nanowires, whose average diameter is 90 nm, is the most uniform. And the average transmittance of prepared film exceeds 85%, and the transmittance at 330 nm wavelength has a maximum value of 89%, higher than the average diameter of 45 nm group of transmittance, but the transmittance in the average diameter of 200 nm group is only 65%.
