摘要：

通过在银纳米棒前驱液中引入柠檬酸钠、双氧水以及硼氢化钠, 成功制备出银纳米三角片. 采用X射线衍射(X-ray diffraction, XRD)、透射电子显微镜(transmission electron microscope, TEM) 和紫外-可见-近红外(ultraviolet-visible-near infrared, UV-Vis-NIR)光谱对样品进行表征. 结果表明, 制备的银纳米三角片的边长约为100 nm, 且为面心立方晶体(face centered cubic, fcc)结构; 银纳米三角片的形貌与银纳米棒前驱液的加入量有关. 通过分析UV-Vis-NIR 光谱, 发现银纳米三角片在830 nm 处具有很强的表面等离子体共振(surface plasmon resonance, SPR) 峰. 因其良好的红外吸收性能, 银纳米三角片可被应用于硅基薄膜太阳能电池的前电极.

Abstract:

Ag triangular nanoplates were obtained by introducing sodium citrate, H₂O₂ and NaBH₄ in the Ag nanobars precursor solution. X-ray diffraction (XRD), transmission electron microscope (TEM) and ultraviolet visible-near infrared (UV-Vis-NIR) spectra were used to characterize the samples. The results indicate that Ag triangular nanoplates have a face centered cubic (fcc) structure, and their edge length is about 100 nm. Morphologies of Ag nanoplates dependes on the different amounts of Ag nanobars precursor solution. From UV-Vis-NIR spectra, Ag triangular nanoplates have a strong surface plasmon resonance (SPR) peak at about 830 nm. Because of the excellent infrared absorption property, Ag triangular nanoplates can be used for top electrode of silicon film solar cell in the future.

Key words: Ag nanobar, surface plasmon resonance (SPR), Ag nanoplate
