研究了硒、碲与醋酸铅在氢氧化钠溶液中，以水合肼为还原剂的水热反应制备铅硫族化合物PbE（E=Se，Te）。在温和的条件下可以得到不同形貌的纳米晶。实验表明，原料和反应温度对目标产物的形成和形貌的控制起着重要作用。在我们的工艺中，铅硫属化物的形成是基于直接元素组合途径。用X射线衍射（XRD）和透射电镜（TEM）对产物进行了表征。
Hydrothermal reaction of selenium or tellurium with lead acetate in sodium hydroxide solution in the presence of hydrazine hydrate as a reductive was investigated to prepare lead chalcogenides, PbE (E=Se, Te). Nanocrystals with different morphology could be obtained under mild conditions. Our experiment shows that source materials and reaction temperature play important roles in forming the objective products and controlling their morphologies. The formation of lead chalcogenides in our process is based on a direct elemental combination pathway. The products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).
