Synthesis and Characterization of Silver Selenide Particles and Bulk

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 Ag2Se 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.
