Open publisher page 0 citations

Abstract

Nanocrystalline Ag_2Se was synthesized via a convenient hydrothermal route at relatively low temperature,using AgNO_3,Na_2SeO_3 or selenium powder as reactant.Several techniques including XRD,TEM and SEM were used to characterize the products.The results showed that the prepared product was proved of orthorhombic Ag_2Se with morphology of irregular nanoparticles and if using different selenium sources and surfactant PVP,the morphologies of the Ag_2Se can be controlled.
