Gold nanorod/molybdenum sulfide core-shell nanostructures synthesized by a photo-induced reduction process.

Coupling of plasmonic nanostructures and semiconductors gives promising hybrid nanostructures that can be used in different applications such as photosensing and energy conversion. In this report, we describe an approach for fabricating a new hybrid material by coupling a gold nanorod (Au NR) core and amorphous molybdenum sulfide (MoS) shell. The Au NR/MoS core-shell structure is achieved by exploiting the hot electrons generated in the plasmonic excitation of Au NRs to drive the reduction of [MoS], which is pre-adsorbed on the Au NR surface, producing a thin MoS layer.
