Synthesis of CdSe nanorods decorated with US nanoparticles and investigation into their optical, electrical properties are reported. CdS-decorated CdSe nanorods were assembled across gold microelectrode pairs, forming a prototype photoswitch, and showed superior photoelectrical property to the nude CdSe ones. Mechanism accounting for the improvement on the photoswitching behavior of CdS-decorated CdSc nanorods was presented as well. The excellent response of CdS-decorated CdSe nanorods to the visible light promises the appealing application in fabrication of photoelectric devices.
