以硒粉、硝酸铅、硝酸银和硝酸锑为原料，NaBH4为还原剂，在160℃水热合成了银和锑共掺的PbSe(AgPb10SbSe12)纳米粉末。分别用X射线衍射仪、扫描电子显微镜、透射电子显微镜和X射线光电子能谱对纳米粉末进行了表征。提出了Ag、Sb共掺杂PbSe纳米粉末的形成机理。
Silver and antimony co-doped PbSe (AgPb10SbSe12) nanopowders were hydrothermally synthesized at 160 °C, using selenium powder, lead nitrate, silver nitrate and antimony nitrate as starting materials, and NaBH4as a reductant. X-ray diffraction (XRD), scanning electron microscope (SEM) equipped with X-ray energy-dispersed spectroscopy (EDS), and transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) were respectively used for characterization of the nanopowders. The formation mechanism of the Ag and Sb co-doped PbSe nanopowders was proposed.
