摘要：
Gold triangular nanoplates with a uniform size were synthesized by a simple seeds-growth method in a lamellar lyotropic liquid crystal(LLC) medium consisting of F127,n-C4H9OH and H2O.The edge length of gold nanoplates can be adjusted from tens to several hundreds nanometers(and even a few micrometers) by varying the concentration of Au3+ and the seeds solution volume.The optical properties of the synthesized gold nanoplates were studied.The vis-NIR spectra of the synthesized gold nanoplates exhibited a good linear correlation between the in-plane plasmon resonance λmax and the average edge length of the corresponding nanoplates.
