Ag۲Se nanoparticles: synthesis, characterization and effect of preparation conditions under ultrasound radiation

چکیده مقاله

A convenient sonochemical process for the preparation of silver selenide (Ag2Se) nanoparticles by using different complexing agents (NH3, citric acid (C6H8O7), potassium thiocyanate (KSCN)) and hydrazine as reductant agent was discovered. It was found that pure Ag2Se nanoparticles were prepared in the presence of KSCN after 90 min of sonication. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analysis. Photoluminescence (PL) was used to study the optical properties of Ag2Se samples.
