Abstract:

Lead telluride nanorods were successfully synthesized by a simple glucose-assisted solvothermal method. The structure characteristics of these as-prepared samples were studied by X-ray diffraction pattern(XRD), field emission scanning electron microscopy(FESEM), transmission electron microscopy(TEM), high resolution transmission electron microscopy(HRTEM) and energy dispersive spectrometer(EDS). The results show that the products are PbTe with a cubic structure. The diameter and length of PbTe nanorods obtained are 50 and 500 nm, respectively. Some reaction factors influencing the formation of PbTe nanorods were systematically investigated. The morphology of the obtained products can be controlled by changing the amount of glucose, the reaction time, the reaction temperature and the amount of polyvinyl pyrrolidone(PVP). The mechanism for the formation of PbTe nanorods is discussed.

Key words: lead telluride nanorods, glucose, solvothermal synthesis, growth mechanism
