Figure 1
(a) UV-vis-NIR kinetics of the reaction of Piper betle leaf extract with aqueous chloroaurate ions. Curves 1–8 correspond to 0, 10, 60, 120, 180, 240, 480, and 720 min after reaction, respectively. (b) Representative TEM micrographs of triangular gold nanoparticles obtained by the reduction of by Piper betle leaf extract. (c) XRD pattern of Piper betel leaf extract reduced nanotriangles with identified Bragg reflections. (d) A high magnified TEM micrograph of the single gold nanotriangles.
