Název v původním jazyce

Simple mechanochemical synthesis, characterization, optical and thermoelectric properties of a nanostructured silver (I) selenide semiconductor

Popis výsledku v původním jazyce

Silver(I) selenide, Ag2Se was very simply and conveniently prepared from Ag and Se powders in a stoichiometric ratio by one-step mechanochemical synthesis after 10 min of milling in a planetary ball mill. The kinetics of this synthesis and the structural, morphological, optical, and thermoelectric properties of the product were studied. XRD confirmed the orthorhombic crystal structure of naumannite, Ag2Se. The electron microscopy revealed that the nanostructured product consisted of isolated rod-shaped particles and agglomerated nanoparticles of irregular shape which formed clusters with a size >30 μm. Crystallinity was inspected by selected area diffraction. For the densification of mechanochemically synthesized powdered Ag2Se, the spark plasma sintering method was applied to prepare a suitable sample for thermoelectric characterization.
