Abstract
Through the seed-mediated growth method in N,N-dimethylformamide (DMF)-water medium using trisodium citrate and poly(vinyl pyrrolidone) (PVP) as stabilizer, Au rhombic dodecahedra with a narrow size distribution (< 5% in standard deviation) and high shape yield (> 90%) could be reproducibly synthesized thanks to the robust formation of rhombic dodecahedra by DMF-water medium and surface stabilization by trisodium citrate. Moreover, the edge lengths of these Au rhombic dodecahedra could be readily controlled from 19 to 67 nm by varying the amount of seeds, concentration of HAuCl4, or both, and thus the localized surface plasmon resonance peak positions of the Au rhombic dodecahedra could be continuously tuned from 532 to 655 nm. © 2013 The Royal Society of Chemistry.
