摘要: 以低毒性的HgO与S,Se,Te单质为原料,乙二胺为溶剂,在室温下合成了汞的硫属化合物纳米材料HgS,HgSe和HgTe,并通过XRD,TEM和XPS对产物进行了表征.结果表明,所合成的产物为六方相α-HgS和立方闪锌矿结构的HgSe和HgTe,且纯度高,粒度分布均匀.对反应的机理进行了初步探讨.

Abstract: An oxide direct conversion route was reported to synthesize the nanocrystalline HgE (E=S,Se,Te) in ethylenediamine at room temperature. Mercury oxide was used as mercury source and sulfur, selenium, tellerium, respectively, as chalcogenide sources. XRDpatterns show that the obtained samples are hexagonal(wurtzite structure) HgS, cubic (zinc blende structure) HgSe and HgTe. The influences of solvent and reaction temperature were investigated and it was found that the ethylenediamine plays a crucial role in the conversion process.
