Abstract: Compositions and methods for fabrication or synthesis of high aspect ratio (up to >150) CdS:Mn/ZnS core/shell nanowires (CSNWs) is disclosed for the first time. The CSNW solvothermal synthesis involved two steps—the formation of Mn doped CdS core followed by the growth of a ZnS outer shell. The nanowire growth process is engineered in such a way that the ZnS layer grows radially onto the prematurely grown CdS:Mn core prior to the formation of its well faceted surface. Transmission electron microscopy (TEM) and other characterization techniques confirmed the formation of uniform, thin (5-8 nm in diameter) CSNWs with high aspect ratio up to >150. This solvothermal method is simple, versatile and useful in a large scale production process to synthesize thin ultra-long CSNWs with and without dopants.
