Abstract
Single-crystalline gold nanorods of average size 121nm x8.4nmwith defect free surface are synthesized with surface plasmon resonance in the near-infrared region. The surface plasmon resonance is readily tunable from 900-1300nm by maintaining the pH of the growth solution while varying the Au<sup>3+</sup>/Ag<sup>+</sup>ratio.
