| Abstract: | Reaction of a tellurium alkaline aqueous solution and Pb（NO3）2 aqueous solution with NaOH and KBH4 produces mirro-crystalline PbTe with a cubic phase by hydrothermal method.The products were characterized through X-ray diffraction （XRD）,scanning electron microscopy （SEM）,and X-ray photoelectron spectroscopy （XPS）analysis.An advantage of the synthesis method was that the PbTe crystallizes well in the alkaline solution.The mechanism for the formation of the PbTe was discussed. |
