Abstract
ⶠBromide ion catalyses the oxidative anisotropic transformation of as-synthesised gold nanorods (GNRs) to spherical shape in the presence of hydrogen peroxide via Au(III)-CTAB complexation. ⶠUV-vis spectroscopic analysis showed the blue shifting of longitudinal Plasmon due to shortening of GNRs. ⶠTransmission electron microscopy (TEM) images further confirmed the sequential shortening of GNRs. ⶠThis anisotropic behaviour provides, the information to the GNRs growth mechanism, as both growth and shortening occurs preferentially at the edge of single-crystalline GNRs in the presence of Brâ ions.
