Template-free ZnS nanorod synthesis by microwave irradiation

Abstract

We report template-free, microwave-irradiation-assisted growth of ZnS nanorods. Using this facile and high yield technique we could grow nanostructures of approximately 50–100 nm diameter and more than 1 µm in length. Effects of microwave power and irradiation time on the growth process were investigated. It was revealed that the time of refluxing plays a vital role in determining the thickness of the rods. This simple technique using a multimode microwave source may prove to be a potential tool for growing similar nanostructures of other oxide-, sulfide- and selenide-based compound semiconductors.
