Abstract Silver(I) selenide, Ag 2 Se 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. The crystal structure, physical properties, and morphology were characterized by X‐ray diffraction (XRD), specific surface area measurements, particle ...

In this study, we report the optoelectric and thermoelectric properties of famatinite Cu3SbS4 that was mechanochemically synthesized in a planetary mill from powder elements for 120 min in an inert atmosphere. The tetragonal famatinite Cu3SbS4 was nanocrystalline with a crystallite size of 14 nm, as endorsed by Rietveld refinement. High-resolution transmission electron microscopy showed several crystallites in the range of 20–50 nm. Raman spectroscopy proved the purity of the synthesized famatinite ...
