A Single-Source Precursor Route to Unusual PbSe Nanostructures by a Solution-Liquid-Solid Method.

PbSe nanowires (NWs) have been synthesized by using a single-source precursor route. Carefully controlling the conditions of individual reactions leads to PbSe NWs with well-defined diameters (8-25 nm) and lengths (100 nm-1 μm). The as-grown PbSe NWs are highly crystalline, defect free, and readily dispersible in organic solvents. The NWs have been characterized by X-ray diffraction and high-resolution transmission electron microscopy. [ABSTRACT FROM AUTHOR]
