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
