Described is a method for preparing crystalline silver nanorods in water, in the absence of a surfactant or polymer to direct nanoparticle growth, and without externally added seed crystallites. The procedure used is one in which a silver salt is reduced to silver metal by sodium citrate under the influence of microwave irradiation. Key aspects for the production of these nanorods are the use of a closed-chamber microwave heating system that allows precise temperature control and judicious choice of the citrate concentration. This novel finding demonstrates the utility of microwave-assisted synthesis and provides a promising method for the preparation of silver nanorods.
