Controllable synthesis of monodisperse gold nanorod with a small diameter of around 10 nm and a largest plasmon wavelength of 1200 nm

The use of 1,6-dihydroxynaphthalene as a reducing agent for the synthesis of gold nanorods can provide facile control over the size and spectrum of the rod with especially a largest plasmon wavelength of 1200 nm and small diameter of around 10 nm.
