Abstract
The one step synthesis of short aspect ratio gold nanorods using gamma radiation method by incorporating cetyltrimethyl ammonium bromide (CTAB) as a directing agent is reported in this communication. In present method of synthesis, isopropyl radical is selectively generated in the system by carrying out radiolysis of aqueous solution containing 2.75 × 10
