中文摘要：

以氯化纳和硒粉为原料，乙二胺为反应溶剂，通过室温合成法制备了硒化银（Ag2Se）纳米颗粒，并首次利用固相反应法，在300℃～600℃烧结范围合成了晶体。结合X射线粉末衍射（XRD）、扫描电镜SEM及透射电镜（TEM）分别对反应产物的相结构和形貌进行了表征。结果表明，室温合成法所得产物为高纯度的正交仪相Ag2Se纳米颗粒，其表面光滑，呈球形；固相反应法合成的样品保持了正交相结构，且Ag与Se的化学计量比基本满足2：1。

英文摘要：

Sodium chloride, selenide powder and ethylenediamine were used as precursors and silver selenide nanometer particles were prepared applying room temperature conversion method. For the first time, silver selenide bulk was synthesized using solid-state method in a sintering temperature range of 300-600℃. Combined with X-ray diffraction analysis, scanning and transmission electron microscopy, the phase and the topography were characterized. The results showed that α-phase AgRSe manometer particles with a high purity and orthorhombic structure were obtained; the bulk maintain a orthorhombic structure and stoichiometric ratio of Ag to Se was 2：1 which suggested that a Ag2Se bulk was prepared successfully.
